摘要: The use of finite-element methods (FEM) for metal-forming problems originated in the 1960s. One first approaches to problem was elastic-plastic method, developed by Marcal and King (1967). Yamada et al. (1968) Lee Kobayashi (1970, 1971) used FEM solve a variety elasto plasticity, such as flat punch indentation, upsetting solid cylinders, extrusion, expansion hole plate. Relatively successful small-strain analysis above processes achieved.
