【Abstract】 The criterion for remeshing and the automatic generating method of new mesh system are studied. The parameter transmitting method for the information transferring between new and old meshes is put forward by using Sherpard shape function. A general remeshing method suitable for two dimensional rigid plastic analysis is derived. The numerical examples show that the method is of high presicion and efficiency.更多还原
