A finite element simulation code of the sheet metal forming process has been developed. This simulation code plays an important role in the computer aided engineering (CAE) system for an automobile parts forming process, which includes the pre‐ and post‐processes. The paper presents the development of an updated Lagrangian type finite element modelling, based on the elastic–plastic (J2 flow law) membrane shell theory. An attempt is made to calculate the strain distribution incurred by peripherally clamped or non‐clamped square plates when impressed by rigid punches. These are the cases of square box‐shape punch drawing and arbitrary shaped panel stretch forming.
