Career Summary

Biography

I am an Early Career Researcher, having received my PhD in Civil Engineering in June 2010 from the University of Minnesota. My involvement in research started at an early age with an appointment as an Undergraduate Research Assistant in the Department of Mechanical Engineering at the University of Minnesota. In 2005, I completed an internship at Barr Engineering Company in Minneapolis. Since completing my postgraduate studies, I have been employed continuously in a position at the University of Newcastle. I first joined the Priority Research Centre for Geo technical and Materials Modelling in July 2010 as a Research Associate (Level B) and then became a Research Academic (Level C) within the ARC Centre of Excellence for Geo technical Science and Engineering (www.cgse.edu.au) at its inception.

Please visit my personal website (www.jimhambleton.com) for more on my background and interests.

Research Expertise
My general areas of interest are in computational plasticity, contact mechanics, geo technical analysis, and analysis of problems involving steady, pseudo-steady, and unsteady plastic flow. My expertise is in modelling problems in geo- and solid mechanics that are characterized by continuous failure and displacement of material via contact with a rigid or flexible object. Specific areas of interest include (1) ploughing and cutting of soils in earth moving operations, (2) installation effects for screw anchors and screw foundations, (3) penetration-based testing for in situ characterization of soil strength and deformability, and (4) soil-wheel interaction for off-road vehicles.

Teaching Expertise
I thoroughly enjoy teaching introductory and advanced courses in geo mechanics, solid mechanics, and numerical methods. I am particularly well-positioned to teach courses in the following subjects, which align directly with my research interests: Undergraduate Level • Statics and Dynamics • Deformable Body Mechanics • Soil Mechanics • Linear Structural Analysis • Matrix Analysis of Structures • Numerical Methods Graduate Level • Continuum Mechanics • Elasticity • Plasticity • Linear Finite Element Analysis • Non-Linear Finite Element Analysis • Contact Mechanics

Administrative Expertise
My administration expertise derives from years of experience in university governance and professional stewardship. I am currently a Member of the Faculty of Engineering and Built Environment Faculty Board. At the University of Minnesota, I was a Member of the Classroom Advisory Subcommittee, a subcommittee of the University Senate charged with providing advice on issues pertaining broadly to teaching and learning in classrooms. My overarching objective in these positions has been to ensure that the representative views of those directly involved in teaching and research are used to shape policy. On a professional level, I currently Chair the local Chapter of the Australian Geo mechanics Society. Part of this role is to actively engage with industry to bring leading national and international researchers to Newcastle to give seminars, short courses and touring lectures (including the Rankine Lecture on behalf of the Institution of Civil Engineers London, the Terzaghi Lecture on behalf of the ASCE, and the E H Davis Lecture in behalf of the AGS). Prior to acting as Chair, I spent three years in the role of Young Geo technical Professional Representative.

Collaborations
My research aims to advance the understanding of how soils are moved and shaped through interaction with man-made objects and machinery. An overarching goal is to develop rigorous, mechanics-based models for predicting soil deformation and the corresponding force requirements or reactions. These problems pose a tremendous challenge due to the confluence of unsteady plastic flow, potentially three-dimensional deformation, contact interaction, material instabilities, and rate effects from inertial forces and hydro mechanical coupling (for saturated or partially saturated soils). Through collaborative research initiatives, I hope to establish new modelling paradigms to help establish accurate, robust, and efficient computational methods. In collaboration with industry leaders and policymakers, I endeavor to realize the full potential of this work as a means of reducing costs and production times, as well as mitigating consumption and pollution.

Conference of International Association for Computer Methods and Recent Advances in Geomechanics, IACMAG 2014, 159-164 (2015)

Ploughing processes are difficult to simulate using conventional approaches due to the occurrence of extremely large, predominantly plastic deformation. Numerical techniques such as the Material Point Method and the Discrete Element Method are, in principle, capable of reproducing the deformation observed in these evolutionary processes, but they are not without drawbacks, the most significant being the large processing times required. This paper presents a new numerical technique for modeling the ploughing process in sands. The method rests on the assumption that deformation occurs in the formof strong discontinuities, or shear bands, and considers the full process as a sequence of incipient collapse problems.Within an increment of deformation, the collapse mechanism furnishing the least resistance is used to update the deformed configuration and evaluate force. The model incorporates the effect of softening within the shear bands, as well as material avalanching observed as the slope of the free surface reaches the critical angle at which instabilities occur. Theoretical predictions are compared to experiments, and the basic similarities and difference are discussed. © 2015 Taylor & Francis Group, London.

Helical anchors, which are mostly used to resist uplift, are deep foundations installed by rotation into the ground. Despite the central role of the installation process, especially with respect to the effect of soil disturbance, relatively little is known about the forces and deformations occurring during installation. An exception is the field verification technique known as torque-capacity correlation, which attempts to relate installation torque directly to uplift capacity. However, there are open questions regarding this approach, since not all significant parameters, such as installation vertical force and helix pitch, are taken into consideration. This could be one of the main reasons behind the wide range of torque-correlation factors reported in the literature. This study presents a three-dimensional numerical analysis of the installation process for helical anchors in clay. The results are synthesised into convenient yield envelopes that predict the relationship between installation torque and normal force as functions of helix pitch, roughness, and thickness. The application of the findings to torque-capacity correlation is also discussed. © 2015 Taylor & Francis Group, London.

Economic growth in Australia and the rest of the world is linked to the scale of construction and mining, and the amount of earth moved each year in these operations is difficult to fathom. When distributed evenly across the world's population, each individual moves several tonnes of earth each year. This paper highlights current and future research initiatives within the ARC Centre of Excellence for Geotechnical Science and Engineering (CGSE) aimed at developing rigorous, mechanics-based models for fundamental ploughing and cutting processes in soils. State-of-the-art physical modelling is integrated with the development of new techniques for analytical and numerical modelling to elucidate and predict the full progression of forces and deformations in both two-dimensional and three-dimensional processes. A new analytical model for cutting in dry sand is presented, and preliminary results from numerical and physical modelling are described. The analyses reveal effects that available models fail to consider and illustrate how the development of rigorous models may facilitate improvements in production and efficiency in earthmoving operations.
