Application and analysis of metal fracture behavior based on FEM calculation

HU Jian-jun1,XU Hong-bin1,JIN Yan2,CHEN Yuan-fang1(1.Department of Material Science and Engineering,Chongqing Institute of Technology,Chongqing 400050,China; 2.Department of Computer Science and Engineering,Chongqing Institute of Technology,Chongqing 400050,China)  
In order to obtain the conformity between FEM analysis and the real condition of the metal fracture behavior,the general judgement method of metal fracture FEM analysis was discussed.The key technology of FEM used for metal fracture behavior was introduced in detail.The general ductility fracture criterion was discussed and a fracture criterion method was put forward.The adjustment and re-meshing of finite element grid for metal fracture behavior and the successful application of FEM technology to metal fracture behavior during extrusion,cutting and stamping were introduced.The key factor of FEM used for metal fracture behavior was acquired.
