Quasi-static analysis of sheet metal forming processes -- a design evaluation tool

Abstract

The implicit time integration technique is the best method known today to analyze the quasi-static formulation for sheet metal forming processes. However, this method has one major obstacle, convergence of the iteration in each load step. Having resolved this issue, Ford successfully implemented a new 3-D analysis code which meets many of necessary requirements for reliability, efficiency and user friendliness for production applications. Examples for analyses of typical automotive body panels by the 3-D code are presented. © 1994.
