【摘要】 本文针对板料成形过程的大变形、起皱、破裂等现象,通过与"轧制、锻压、拉拨"等"块料"成形问题的比较,分析板料成形中特有的力学性质,并着重讨论了在有限元计算中需注意的问题和应该采用的方法更多还原

【Abstract】 Comparing with rolling,forging,extruding etc.bulk forming processes,this paper analyzed the characteristic mechanical problems,e.g.,large deformation, wrinkle,fracture in sheet forming process.Some problems in need of attention and some methods in finite element analysis were discussed emphatically.更多还原
