【Abstract】 The theory and method of finite element analysis of sheet metal forming based on deformation theory was explored, and the computer program was implemented. The comparison between the results obtained from this method and incremental approach indicated that this method can analyze the deformation of sheet metal forming part. Because of its rapid computing speed and simple modeling requirement, this method can be used to evaluate the formability and process parameters of sheet metal forming parts at the early design stage.更多还原
