Flange Wrinkling in Deep-Drawing: Experiments, Simulations and a Reduced-Order Model

Flange wrinkling is often seen in deep-drawing process when the applied blankholding force too small. This paper investigates plastic of flange under a constant force. A series experiments AA1100-O blanks are conducted with different forces. The critical cup height and wave numbers for each case established. reduced-order model developed using energy method, which implemented to predict sheet by incrementally updating geometry material hardening parameters during drawing process. finite element ABAQUS/standard simulate predicted from compared experimental results, demonstrates accuracy model, its potential application fast prediction
