Simulation for Cutting Deformable Model Based on X-FEM

An extended finite element simulation (X-FEM) framework for cutting models is presented. Based on the existing work, a simplified approach to deal with the multiple cuts in a element is proposed. Meanwhile, the simulating method of cutting large deformation models is expressed for the application of computer graphics and virtual reality. Other related issues are also discussion, such as the mass matrix calculation and the approximation function of cutting elements. Experiments prove that the proposed method can effectively improve the efficiency and realistic of the cut simulation in this paper.
