| Abstract: | This paper introduces the basic theory on dynamic explicit finiteelement method and expounds several critical techniques such as contact and friction algorithms,simulation or determination methods on wrinkling and cracking,simulation algorithms on springback etc.Finally,by introducing three groups of benchmarks and the simulation results of participants in NUMISHEET’99,this paper presents the application of finite element simulation technology in the field of sheet metal forming. |
