Model-element analytic method for plastic forming of material

Abstract

MEM (model element method) is proposed to resolve the present difficulties and problems in CAE about plastic forming of material. There are four advantages when MEM is integrated with FEM (finite element method) and UBM (upper boundary element method). First, it can make full use of their own advantages and overcome their own disadvantages; second, it can analyse material plastic fluid expediently; third, it can optimize design; finally, it can improve technological content and application effect of CAE software. Based on introducing the principle of MEM briefly, features and applications of MEM are pointed out. In conclusion, a new analysis method for plastic forming comes forth.
