Analysis of Crack Geometry using Distributed Visualization Software

The paper presents the development of a visualization algorithm for cracks propagating in mono-dispersed particulate media. The algorithm is based on local Voronoi decompositions generated according to the lattice topology employed in parallel computations of the discrete element method. The developed algorithm is implemented in the distributed visualization software VisPartDEM. Crack propagation observed in elastic solid problem exhibiting non-uniform distribution of fracture force values is considered to validate the performance of the proposed algorithm and the developed software. The results of performed benchmarks are compared with those obtained by using a standard global Voronoi algorithm.
