Simulating Brittle Fracture with Material Points

Large-scale topological changes play a key role in capturing the fine debris of fracturing virtual brittle material. Real-world, tough fractures have dynamic branching behaviour but numerical simulation this phenomena is notoriously challenging. In order to robustly capture these visual characteristics, we simulate fracture by combining elastodynamic continuum mechanical models with rigid-body methods: A damage mechanics (CDM) problem solved, following impact, crack propagation tracking field. We combine result elastostatic model novel technique approximate cracks as non-manifold mid-surface, which enables accurate and robust modelling material fragment volumes compliment fast-and-rigid shatter effects. For enhanced realism, add detail, incorporating particle damage-time inform localised perturbation surface artistic control. evaluate our method numerous examples comparisons, showing that it produces breadth effects low resolution require much less time compared fully simulations.
