Meshless Fracture Simulation Method Suitable for Parallel Computing

Abstract

This paper proposes a stress-based elastic body fracture simulation method suitable for parallel computing using GPUs. By integrating three techniques: Position Based Dynamics for simulating elastic bodies, a meshless stress calculation method, and a crack propagation and fracture surface generation method using surfels and crack tip models, dynamic and flexible fracture surface generation can be efficiently processed. This resolves the trade-off relationship between computational cost and crack shape representation ability that conventional fracture simulations have. In addition, the proposed method is implemented using Compute Shader, and experiments using GPUs confirm that it is possible to achieve both detailed fracture surface representation and real-time processing.
