FEM

This paper presents a spatial reduction framework for simulating nonlinear deformable objects interactively. This reduced model is built using a small number of overlapping quadratic domains.

We study how to make thin-plate fracture animations more realistic by three novel techniques: a stress relaxation method; a fracture-aware remeshing scheme based on constrained Delaunay triangulation; and a multi-layered model to simulate complex fractures across thin layers.
