Geomechanics studies the behavior of granular materials when stress is applied, with the objective of creating models useful to civil engineering. In situations where a granular medium is over-stressed and fails, strains inside the material have been observed to localize. This means that there is no longer homogeneous deformation - this causes problems both in the modeling of such phenomena as well as the experiments to investigate such phenomena. The experimental challenge has been overcome with the advent of non-destructive 3D imaging techniques such as x-ray tomography.
This PhD project will investigate such visualizations for time-dependent datasets of approx. 100,000 grains in approx. 20 different states for which the initial positions and the 3D displacements and rotations are known.
The PhD project will investigate the application of interactive 3D visualization techniques to enable material scientists to get a deeper understanding understanding of the material's behavior.
