Summary:

This paper describes the deformation analysis of hemispherical punch stretching and square shell drawing, using 3-D finite element program "ROBUST". The effects of material properties and process factors on cup height to punch force relation, and strain distributions on formed parts were investigated. The calculated values give considerably good agreement with experimental measurements from LDH, FLD and square shell tests. The results can be expected to contribute to predictive evaluation of forming limits using computer simulation
