A finite element program based on the nonlinear shell theory, membrane plus bending, and the flow theory of plasticity has been developed to analyze stresses and deformation during the three stages of the stretch-draw forming process. A surface contact problem with friction is formulated in this paper and solved by means of the developed program. It is applied to two actual body outer-panels in this paper to demonstrate the capability and features of the program. Computing time for an overall analysis of these three forming stages of the stretch-draw forming process is reasonable. Therefore, it is practical to use this program for evaluation of design of the forming process.
