Career Summary
Biography
Klaus Thoeni holds a Ph.D. and a M.S. degree in Civil Engineering of Graz University of Technology in Austria and has been working with advanced numerical methods (BEM, FEM, DEM) and their application to underground excavations, rock mechanics and structural analysis for more than 15 years. In July 2010, he moved to Australia and took a position as research associate at the University of Newcastle. Since then, he has been mainly working on industry funded projects.
He has also joined the development team of the open-source software YADE, which is an efficient numerical tool for simulating the dynamic behaviour of geomaterials by using the Discrete Element Method. Prior to this, he was a research associate at the Institute for Structural Analysis at Graz University of Technology where he focussed on the European project SeRoN. He was strongly involved in the initial stage of the project the identification and classification of critical infrastructures (D100, D200).
He obtained his Ph.D. in Civil Engineering in September 2009. During his Ph.D., he worked as a full time research and teaching assistant at the same institution. As a teaching assistant, he taught structural analysis (statics and dynamics of structures) and numerical methods (FEM, BEM) and he supervised several bachelor and master projects. As a researcher, he was strongly involved in the integrated European project TunConstruct and the application of the Boundary Element Method to anisotropic material, piezoelectricity and non-linear problems. He was in the development team of the research software BEFE++, which is a new generation numerical analysis tool for underground excavations.
Research ExpertiseDr Thoeni's areas of expertise are in numerical methods (BEM, DEM, FEM) and their application in structural analysis, rock mechanics, geomechanics and mining. He has extensive knowledge in the analysis of tunnelling and underground excavation problems with the Boundary Element Method and Finite Element Method (including the coupling of the methods) and in the simulation of rockfall protection systems with the Discrete Element Method. Other areas of general interest are photogrammetry, programming, parallel processing and open source software (Linux).
Teaching Expertise
Dr Thoeni was strongly involved in teaching structural analysis (statics and dynamics of structures) and numerical methods (FEM, BEM) at the Institute for Structural Analysis at Graz University of Technology, where he supervised several bachelor and master projects. He is currently supervising FYP projects and teaching ENGG1002 and CIVL2050 at the University of Newcastle.
Administrative Expertise
Dr Thoeni was second deputy head of the Institute for Structural Analysis at Graz University of Technology were he was computer and network administrator and fire warden. Currently he is a member of the Cloud Migration Senior User Group (SUG) representing the School of Engineering.

Three-dimensional discrete element simulations are performed to better understand the impact-induced complex fragmentation process of marble spheres. A 3D clumped particle method is used and a new calibration procedure to match both the quasi-static and dynamic mechanical behaviors of marble is proposed. The impact simulation results show that radial macrocracks occur, which break the intact marble spheres into large orange-slice-shaped fragments. Secondary macrocracks occur for impact velocities larger than 9¿m/s, and the fragment size is further reduced. The fracture mechanisms due to local damage, radial, and secondary macrocracks significantly affect the impact process, energy dissipation, evolutions of the masses of the first and second largest fragments, and damage ratio. The numerical model is able to accurately capture all mechanisms, from local damage to disintegration, of the impact-induced fragmentation. Due to local damage and macrocracks, the obtained fragments consist of large and small fragments. The fragment size distributions based on mass and number can be fitted using a generalized extreme value law. The numerical predictions indicate that the translational velocities of some small fragments can be significantly higher than the impact velocity due to the instant high-tensile stress wave near the contact area. The results also suggest that there is no correlation between fragment mass and fragment kinetic energy.

This paper presents a new methodology for estimating the expected energies and first impact distances at the base of a rock cliff, subject to the geometry and properties of the cliff and the representative block being known. The method is based on a sensitivity analysis, conducted by means of kinematic simulations and carried out for a large range of input parameters and their combinations, taking into account the uncertainty associated with their estimate. The proposed approach is validated by comparing predictions to experimental data and shows great potential for a quick qualitative hazard assessment.

The test involves the titling of a specifically designed split-box and measuring the angle at which the upper half of the box slides off. This angle can be interpreted as the peak friction angle of the sample for a low stress state. Experimental tests and numerical analyses using the Discrete Element Method (DEM) are carried out and compared. The study is carried out for two different materials, a rounded and an angular aggregate. It is shown that rolling resistance is needed to match the experimental results if only spheres are used but this is not the case for non-spherical particles. © 2015 Taylor & Francis Group, London.

A contact law using a linear hysteresis model for normal contacts and a Mohr-Coulomb model for tangential contacts is used. In addition, two dissipative laws are introduced consisting of a moment transfer law and normal viscous damping law. One of the aims of this study is to investigate if the contact law enables a realistic modelling of the rebound characteristics of a block during impact on a muckpile. A parametric study is carried out in order to investigate the influence of the constitutive model parameters and the presence of clumps. Numerical predictions are compared to experimental results. It is shown that clumps in the muckpile are essential to reproduce realistic results. © 2015 Taylor & Francis Group, London.

The falling rock is represented by a rigid assembly of spheres whereas the slope is represented by triangular elements. Energy dissipation during impact on the slope is considered via friction and viscous damping. The drapery is represented by a set of spherical particles which interact remotely. The numerical model is used to investigate the efficiency of a drapery system. Various simulations with two different block sizes are performed and the numerical predictions of simulations with drapery are compared to simulations without drapery in order to assess the performance of the protection system.
