Engineered for building ideas
Civil Materials Engineer Igor Chaves has a precise focus for his research goals. He wants to build ideas.
As a youth, Igor was engrossed in programs on the Discovery Channel focussed on building large structures which sparked his desire to make his mark on the world and to be a part of something that built things for the community. When it came time for tertiary study, Igor’s exemplary school results left the doors pretty wide open to study anything he desired. “I went to the Federal University of Vicosa (Brazil) to check out what was on offer for an undergraduate degree. I looked at Maths, Physics, Law, Economics and nothing was quite right. So I went over to Architecture because I wanted to design, I wanted to create things, and by chance, a lecturer saw me and said “Before you make the decision, let me put you in touch with a consulting Civil Engineer as he’ll be happy for you to hang around the office and see what they do.”
This chance meeting led to Igor working as a volunteer Construction Engineer for two and a half years while he studied Bachelor of Engineering (Civil). “I went to Uni in the morning, and worked in the afternoon.” For most people, that would be a full schedule: but not Igor. “I was also an indoor rock climbing instructor in the evenings and used to play classical guitar at weddings and theatres over the weekends to help give me a little bit of pocket money,” he grins.
“Studying a Bachelor of Civil Engineering, and being exposed to the construction management as well as the rock climbing made me realise that I don’t actually have to build ‘things’ – I can build ideas and these ideas can be applied by lots of people.”
Before graduating, Igor was head-hunted to work as an industrial researcher for two and a half years whilst being offered the top scholarship in the country to complete a Master of Structural Engineering in Brazil. Then Australia came calling, well, Newcastle in particular. “In 2009 I got a phone call from a guy called Rob Melchers from Australia. He said he’d heard good things about me and had an offer for me. I took up his offer and here I am,” Igor says.
A PhD at the University of Newcastle under Professor Melchers has led to a career as a research academic at UON. Although Igor’s career seems like a series of fortuitous events he’s quick to add that it’s all part of his plan: “It’s all mapped out,” he says with a smile. “Ever since I got into University and I had that click: ‘I’m going to build ideas’ I just drew a career path and followed it. I was very fortunate, because I had mentors that I wished to learn from that I’ve met along the way.”
Rusted on Research
A life-long learner, Igor’s career path has led him to explore rust and corrosion in his current research, and it seems a natural progression. “When I was doing Construction Management I observed that the most complex thing to handle was not the design, but the implementation and operation of that design. Making sure that during that process you guarantee longevity so that when you operate what you built you don’t have deterioration.”
“When I moved into building ideas, the same philosophy applied. We had to come up with formulas for people to use so that when they use it, the risk of that formula giving you a bad result was minimised”.
“I did my masters of Structural Engineering on minimising risk where I undertook prototypes testing with new products and computer analysis. I got a handful of results which took two years to obtain, but then those results were going to be the basis of the standardised design equations that went into the Brazilian construction codes (specifically the Brazilian Standard for Structural Steel Design – NBR 08800 2009). This made me think, ‘how can we generalise this scenario from a handful of results? Can I quantify the risks somehow?’”
“So I started teaching myself about structural reliability analysis which is the same methodology applied by Prof. Melchers’ group here in Newcastle. In fact Rob Melchers wrote the book that I was studying at the time!”
“When Rob called me he said, ‘What do you know about corrosion?’ and I said ‘Squat, I have no clue, I’m a Civil Engineer’ so he said that was good as he wanted someone with practical experience. The science is already established, we don’t reinvent the science. As a civil engineer I don’t care about what caused the corrosion – we’re concerned about what happens to structures over time. We need to quantify the risks of the structure becoming unsafe and killing people.”
Global collaboration
Igor and his team rely on published information from experts, and where that’s not available, they collaborate with world-leaders to get the information they need. “There are a number of colleagues across the globe we’re working with,” he says.
“We’re working alongside scientists and relying on published material – or collaborating with chemists and computer scientists, microbiologists if we don’t have the data or expertise. The key thing is understanding the phenomological side of each of those variables, where it comes from, and finding the experts to collaborate with.”
During his PhD long-term corrosion of steel immersed in marine environments Igor noticed an interesting pattern with welds. “I noticed that steel on welds corrodes faster than non-welds,” Igor explains. “This can lead to catastrophies like massive oil spills, even from a very small hole in one area.”
“Assuming you have the best welder, the best material and the best practice, you will still have microstructural variations in the material itself. You don’t change the chemistry, but you can still change the shape of the crystals and how they pack up. There will be a very small area where there’s different shapes and sizes and that causes the corrosion to accelerate. We’re working on joining without welding, but even with bolting there’s a crevice which can lead to even more problematic scenarios. If you’re going to weld you need to do pre- and post-heat treatment of the welds very well to minimise that problem. Your choices are to minimise the problem or protect the area with mitigation mechanisms.”
“If you consider that risk is the probability of something happening, times the consequence of something happening, the sheer magnitude of such consequences of these failures hugely exacerbates the risk you can consider,” Igor concludes.
Taking academia to industry
Igor often attends International Conferences where major oil companies sent representatives to try and learn from academia in order to forge strong industrial ties. “With their infrastructure, such as North Sea Oil Platforms, it’s a major cost to them if they need to stop work to make repairs. The standard method was to identify a problem, then cut it out to repair – but this leaves the problem in that there are now two welds – susceptible to corrosion. I try to counter-argue in that it’s a short-term solution and that we can help prolong the time between repairs.”
There are three main components you should look at when trying to predict at corrosion: variables in the environment, the material itself and the corrosion mechanism. That’s where Igor’s research focus is honed.
Igor works to convince industries to invest a little in his research – to make massive gains in their bottom line. “Even if they just invest one percent of the cost of a project it can make a high impact in the long-term. Instead of trying to replicate situations in the lab, we focus going out into the real world and getting the empirical evidence for each of the variables and then bringing it into the lab.”
A 2016 Early Career and Innovation Excellence award from the Faculty of Engineering and Built Environment is the latest in a string of awards and accolades this early career researcher is gathering. “I just believe that working hard will attract just rewards,” he shrugs and smiles.
Having been nurtured under a series of mentors, the next leg of Igor’s journey is to inspire Research Higher Degree candidates with three PhD scholarship opportunities at UON. “We’re now even working with the defence industry to find the solutions to their problems. It’s an exciting time to be researching at the University of Newcastle.”

Career Summary
Biography
In a general form interest in science, particularly technological and scientific research, has always been the main goal in my professional career plan. Allied to the need of specialised learning, I understand that academic research can provide a level of knowledge to face the professional challenges of the present world.
I am currently an Associate Professor of civil structural materials engineering at the University of Newcastle - Australia, where I have been awarded a PhD in 2013 for developing novel approaches to structural steel corrosion analysis and prediction. I initiated my studies on steel structures as a research trainee in 2004 at the Federal University of Vicosa - Brazil, where I graduated as a civil engineer in 2007. My interest for engineering scientific research lead me to the EESC University of Sao Paulo, Brazil, and as result of completing a master’s degree in structural engineering in 2009, design guidelines for cold-formed composite steel and concrete beams were added to the Brazilian Standard of Steel Design.
Research Expertise
- Corrosion and Deterioration Modelling
Defined as the destruction of a material due to its reaction with the environment, corrosion poses a serious threat to new and existing infrastructure. Understanding such phenomena is pivotal when considering long term prediction of structural service life. - Infrastructure Engineering and Asset Management
Integration of multidisciplinary strategies to predict the uncertainties surrounding an asset's structural integrity for sustaining public and private infrastructure, such as water distribution networks or railways, has been proven to be pivotal in modern engineering planning, assisting adequate allocation of resources and more robust decision making. - Numerical and Computational Methods Applied to Structural Engineering
Once real life applications adopt differential equations for elements of scientific nature, engineering computational methods is a powerful tool for approximating accurate solutions for such complex engineering problems. - Experimental Methods and Material Analysis of Structures
Understanding modern engineering experimentation including design, system calibration, data acquisition, analysis and presentation is a key skill for any academic engineer. - Structural Stability and Evaluation of Steel Elements and Composite Systems - Theory and Design
The key to efficient structural design is the optimization of the mechanics, properties and behaviours behind the materials and shapes of structural elements. Understanding your structure in accordance with the applicable codes of practice a more reliable, efficient and durable structure can be built.
Teaching Expertise
Teaching is a special calling and for the strong hearted, encompassing many values such as: achievement, compassion, creativity, duty, excellence, growth, knowledge, leadership, perseverance, courage and vision. To teach is to reflect to the younger generation such values so that high standard professionals can have a solid moral base in which to conduct their responsibilities towards society. Subjects of Expertise Include:
- Statics and Engineering Mechanics
Introduces basic principles of engineering mechanics, emphasising upon the gaining of real understanding of the laws and principles of mechanics and the ability to analyse and solve problems in mechanics. - Engineering Computations and Probability
Understanding and implementing algorithms for a variety of problems where approximate solutions are obtained, the subject introduces the principles of engineering computations and probabilistic statistics, providing solid foundation for later year courses in water, structural and geotechnical engineering. - Theory of Structures
Covers advanced methods of analysis for structural systems, emphasising principles of structural analysis of isostatic and hyperstatic elements, plastic design theory and bounding problems. Providing solid theoretical understanding and capability to solve a vast range of structural design challenges. - Civil Engineering Materials
Professionally capacitate students with understanding of the fundamental, engineering related, issues surrounding the use of Civil Engineering Materials and explain the production and/or manufacturing methods associated with these materials as well as describe and characterise some of the variability and uncertainty associated with them in order to critically analyse the limitations of these materials under various loading circumstances. - Steel Design
Capacitate students with in-depth skills of assimilation of data, determination of load combinations and design of steel structures and elements by applying knowledge from previous courses, developing necessary professional judgement to produce articulate and concise documents which convey evidence-based understanding of structural steel design concepts. - Reinforced Concrete Design
State of the art in-depth training of structural design skills for reinforced concrete and pre-stressed concrete members. Topics include efficient structural design optimisation of the mechanics, properties and behaviour behind the reinforced concrete material and shapes of structural elements in accordance with the applicable codes of practice.
Administrative Expertise
- Construction Management
The combination of theory with practical knowledge makes a firm ground for the practice of engineering over a range of problems. The application of planning, designing, constructing, maintaining and operating infrastructure while protecting the public and environmental health were some of my responsibilities during the period of two years in which I was employed by a construction execution and consulting firm. Responsible for managing and coordinating several local and interstate sites, administrative skills were essential to ensure efficient, effective, secure and professional execution of the company's infrastructure projects.
Duties involved: Technical supervision of all structure construction; Operative oversight of standard of quality required by the Standards and Norms in regards to quality control; Operative oversight of standard of quality for all aggregates and reinforcement steel purchases; Quality control of all sites temporary installments and supervision of working force; Operative supervision of all exterior finishing work, including insulation, cladding and roofing; Maintain daily records of each construction site and report back to office; Gather periodic photographic records of each construction stage and report to office; Development of several small town urban development plans; Assist in overall project legal aspects, design, budgeting, drawing and execution.
- Program Convenor (Bachelor of Civil Engineering)
Since appointed in 2020 by the Faculty Pro Vice-Chancellor I have held overall responsibility for the management and quality of a program (and the courses offered within that program) leading to an award of Bachelor of Civil Engineering with Honors at The Newcastle Australia Institute of Higher Education.
Duties involved: Writing the Annual Report on Program for submission to the Faculty Board meeting; Overseeing the development of the documentation required for an external review of the program; Assisting Course Coordinators for core courses to ensure congruence of assessment tasks with the learning objectives, and that the instructions, requirements and criteria are clear, appropriately weighted and timed; and any other program related activity as required by the Faculty Pro Vice-Chancellor in which the program exists or is the lead Faculty for a combined degree.

Typically, they are galvanized steel, sufficiently strong to provide continuity for transmission of direct and shear forces. However, field observations show they are prone to long-term corrosion and this can have serious structural implications under extreme events such as earthquakes. Opportunistic observations show corrosion occurs largely to the internal masonry interface zone even though conventional Code requirements specify corrosion testing for the whole tie. To throw light on the issue electrochemical test for 2 grades of galvanized ties and 316 stainless steels combined with three different mortar compositions are reported. Most severe corrosion occurred at the masonry interface and sometimes within the masonry itself. Structural capacity tests showed galvanized ties performed better than stainless steel ties in lieu of stainless steel R4 class ties presenting significantly greater relative losses of yield strength, ultimate tensile strength and elongation structural capacity compared to R2 low galvanized and R3 heavy galvanized tie classes.

[more] The critical role of manganese sulphide (MnS) inclusions for the initiation of the short-term growth of pitting or localized corrosion of low carbon steels has long been recognized. Classical results show that pitting probability and pitting severity increases with increased sulphide concentration for low carbon steels as a result of magnesium sulphides acting as local cathodes for initiating pitting corrosion. However, the iron carbides (cementite) in steels can also act as local cathodes for initiation of pitting corrosion. Herein it is proposed that there is competition between pits for cathodic area and that this will determine the severity of pitting and general corrosion observed in extended exposures. Preliminary experimental data for immersion exposures of up to 56 days in natural seawater of three low carbon steels show, contrary to conventional wisdom, greater pit depths for the steels with lower S content. However, the pit depth results are consistent with lower C/S ratios. This is considered to support the concept of cathodic competition between C and S. It is proposed that this offers explanations for a number of other phenomena, including the thus far unexplained apparently higher reactivity of some MnS inclusions.

T... [more] The longer-term serviceability and structural safety of steel infrastructure exposed to seawater conditions may be affected by global warming and by seawater nutrient pollution. These may affect abiotic and biotic (microbial) corrosion. A model for long-term corrosion is developed from data obtained from steel piling exposed for 33 years in a seawater harbour. The effects on corrosion losses on the structural reliability of steel sheet piling as used in harbours world-wide were investigated as a function of seawater temperature rise from global warming and of seawater nutrient pollution. The results show that structural reliability is more sensitive to likely nutrient pollution than to predicted increases in seawater temperature, noting also that global warming also could increase nutrient pollution from anthropological sources.

[more] The quantification of mass loss, surface topography, depth of pitting, and localized corrosion for steels subject to marine corrosion requires the removal of rusts, preferably without causing additional mass loss, pitting, or other damage. Conventional procedures using inhibited hydrochloric acid or Clarke's solution are shown to remove short-term marine rusts but also to cause new corrosion including pitting and related rust products. Both increase with longer exposure to the cleaning solutions. Water washing with soft water left calcareous materials on the metal surface. Ultrasonic removal did not cause additional corrosion but was effective only for very light rusts. Although relatively slow, electrolytic cleaning (electrolysis) produced clean surfaces without new corrosion.

[more] Natural deterioration of mild steel exposed to marine environment compromises the long-term integrity, serviceability and safety of new and existing infrastructure and increases the risk of structural failure. Welded structures are known to be prone to even higher risks as a result of adverse effects of pitting corrosion in weld-heated areas. A bi-modal model has been shown recently to be a better description for the long-term development of the maximum depth of pits. Also, the statistics of pit depth have been shown to be better represented, for long term exposures, by the Frechet extreme value distribution. Both new developments present challenges for structural reliability analysis. Herein a linearization is used to represent long-term development of pit depth. It is shown that data for maximum pit depths can be separated into those with Gumbel statistics and those for which a Frechet distribution is more appropriate. An example is given for the reliability analysis of a welded pipeline subjected to localized corrosion. The effect of random variable uncertainty is assessed using a sensitivity study. Results show the considerable influence on the probability of failure of pit diameter and the parameters describing the pitting corrosion model. © 2014 Elsevier Ltd.

Herein maximum pit depth quantification and its development with time are considered for samples taken from longitudinal welds on 33-year-old tubulars exposed in Newcastle Harbour. Relationships between pit depth and material metallurgy and corrosion properties were investigated by means of standard macro-etching, rest potential and zero resistance ammetry techniques. It is considered that the observed results are the result of the lack of homogeneity at the corrosion interface caused by differences in grain size, grain structure and the potential for pitting to occur preferentially along boundaries. The results are compared to measurements for longitudinal welds obtained previously on samples of API X56 Spec 5L pipe exposed in similar waters for up to 3?5 years, showing a reasonable degree of consistency between the two sets of data. The reasons for this are discussed. © 2013 Institute of Materials, Minerals and Mining.

The study is based on experimental results for connector resistance (push-out) and for four full-scale beam bending tests. The accuracy of analytical design equations is evaluated by comparing their predictions with experimental results. Model bias and model uncertainty of analytical design equations are evaluated. The uncertainty in design variables (steel and concrete resistance, dead and live loads, model errors) is taken into account, and reliability index of code-compliant beams is evaluated. Results show that the models for shear connector and for beam bending resistance are fairly accurate, and represent very little contribution to problem uncertainty and failure probabilities. Results show that for practical beam lengths, full material interaction is guaranteed, and failure is dominated by bending. Reliability indexes of the order of 2.2 to 2.8 are obtained, reflecting reliability of the design procedures studied. These values are low, in comparison to target reliability levels of 3.0 used in code calibration, and should be interpreted carefully in future code revisions. Copyright © 2010 by ABCM.

[more] Severe localized corrosion has long been considered the main cause for containment loss of steel assets such as pipes and tanks, particularly as caused by pitting corrosion on or around weld zones. The weld and heat affected zones for welds in steel structures are known for their higher rate of localized corrosion but there is still some controversy about the specific mechanics causing this phenomenon. This paper overviews the weld corrosion literature that has considered the possible mechanisms involved and the associated material and environmental conditions. Experimental observations are then presented on the metallographic analysis of five separate grades of low-carbon steel. The possibility is examined whether there is a likelihood of greater pit depths being associated with the weld and heat affected zones and whether they can be considered the result of the presence and influence of macro-galvanic cells within the steel matrix. Also, the possibility of localized corrosion being the result of thermal microstructural gradients produced during the welding process is discussed. |

[more] Increasingly climate change, including the possible rise of seawater surface temperatures is causing some concern regarding the integrity of commercial and industrial structures in marine exposed environments. Structural integrity (serviceability and safety) may be compromised by the increased rates of corrosion reactions caused by increased average temperatures. Immersed structural systems also may be prone to microbiologically influenced corrosion. In this paper, three different extrapolation techniques are used to model expected corrosion loss. They are based on the same set of short-term empirical mass loss data for 1 year exposures. The results are compared with mass loss data obtained from steel piling exposed for 33 years. It is shown that the extrapolations from short term data can be very significantly in error compared with actual observations and with better modelling approaches. The effects of temperature increase and of increased microbiological influences are considered as part of the investigation.

[more] The apparently premature corrosion of steel reinforcement in reinforced concrete structures exposed to marine environments continues to be a matter of concern in practice despite decades of research effort and much research funding expenditure and despite much practical experience. Herein results are reported of a long-term (10 year) study of the influence of alkalis on the corrosion initiation and progression of 6mm diam. reinforcing bars centrally embedded in 40x40x160mm concrete specimens. These were made with seawater as mixing water and with a variety of mix proportions including some with added alkalis. All were equally well compacted by vibration. After 10 years continuous exposure in a fog-room only a limited amount of corrosion initiation was observed. These results are in stark contrast with those reported in the famous paper by Shalon & Raphael (1959) who found serious corrosion of reinforcement after only 1-2 years exposure for all mixes. It is shown herein that the corrosion loss trends in those tests are similar to those of steel exposed directly to seawater. This indicates that in the 1959 tests the concrete provided little protection against reinforcement corrosion. The reasons for this are considered herein and the practical implications discussed.
