Fast Remeshing-Free Methods for Complex Cutting and Fracture Simulation
SessionDoctoral Consortium
DescriptionSimulating complex cuts and fractures robustly and accurately benefits a broad spectrum of researchers. We develop a graph-based Finite Element Method model that reformulates elastic strain energy for fracture simulation and adds negligible overhead over FEM. It models fracture on the graph induced in a volumetric mesh with tetrahedral elements. We relabel the edges of the graph using a damage variable to propagate the fracture. We enhance this method with probabilistic damage mechanics to model fracture in materials with impurities. We combine graph-based FEM with Galerkin multigrid to run fracture simulations at an interactive rate even for high-resolution meshes.
