By introducing rigid plastic constitution relationship, the numerical manifold method (NMM)analyzing system for simulating the metal forming process is put forward. The remeshing problem for simulating the metal forming process is also studied.

• 通过引进刚塑性本构关系,建立了金属成形过程的数值流形方法的分析体系,并研究了金属成形过程模拟中的网格重分问题。
