In this paper, a particle-based framework is presented to simulate the fracture phenomenon in computer graphics field. First, the object is represented as discrete particles, and then we introduce the Extend Discrete Element Method (EDEM) simulation to describe the interactions between neighbouring particles based on the material mechanics analysis. To process the fracture, a reverse idea to traditional method is used to cooperate with auxiliary cone algorithm, which called anti-fracture mechanism. The physical computation is executed on the GPU with CUDA and a uniform grid data structure is used in order to search the neighbouring element effectively. Experiment results demonstrate the feasibility and effectiveness of our method.
