Figure 1 : A metal ball tearing a paper sheet. We use FEM to simulate paper and a 2D constrained Delaunay triangulation to adaptively refine the mesh near the potential crack boundary. This allows us to provide more fracture details with an affordable computational cost. Abstract The fractures of thin plates often exhibit complex physical behaviors in the real world. In particular, fractures caused by tearing are different from fractures caused by in-plane motions. In this paper, we study how
more &raquo; ... make thin-plate fracture animations more realistic from three perspectives. We propose a stress relaxation method, which is applied to avoid shattering artifacts after generating each fracture cut. We formulate a fracture-aware remeshing scheme based on constrained Delaunay triangulation, to adaptively provide more fracture details. Finally, we use our multi-layered model to simulate complex fracture behaviors across thin layers. Our experiment shows that the system can efficiently and realistically simulate the fractures of multi-layered thin plates.
