Improved numerical constraint disposal method for process conditions in sheet metal forming simulation

The constraint force generated by process conditions, such as drawbead resistance and boundary friction are generally considered as positive force in dynamic explicit finite element method, which actually are not in accord with realistic effect. A constraint disposal method for constraint force in s...
