A LAGRANGIAN ARBITRARY TRIANGULAR MESH FINITE VOLUME METHOD FOR NUMERICAL SIMULATING 2-DIMENSIONAL HIGH VELOCITY IMPACT PROBLEM
Li Yinfan, Liang Zhenxuan, Tan Qingming
CHINESE JOURNAL OF COMPUTATIONAL PHYSICS    1995, 12 (4): 433-441.  
Abstract245)      PDF (564KB)(764)      
In this paper, a lagrangian arbitrary triangular mesh finite volume method for numerical simulating 2-dimensional high velocity impact problem is described. The elasticity and plasticity of material are considered. Some computational results of several impact examples are shown.
