摘要：

本文综述近年来有限元法(侧重刚塑性有限元法)在模拟金属塑性加工过程方面的应用。其发展大体说来有两个方向,一是对愈来愈多的塑性加工工序用有限元法进行分析计算,另一是开拓除计算变形载荷以外有限元模拟的新用途。 1982年在美国首次召开了国际工业成形过程数值方法会议。会上交流的论文绝大多数采用有限元法,分析对象多数是金属塑性加工问题。回顾刚塑性有限元法在塑性加工方面应用的发展,粗略地说,有两个方向:一是应用这数值方法分析塑性加工的各种不同的工序,以获得变形力学诸参数,主要是求变形载荷、压力分布等,在这过程中不断丰富发展有限元理论和技术;另一是为这方法开拓求变形载荷以外的新用途。下面分别予以介绍:
