SME MF98-221

Wrinkling is one of the major defects in sheet metal forming. The ability to accurately predict the occurrence of wrinkling is critical to the design of tooling and processing parameters. An analytical method for predicting the onset of flange wrinkling is presented here. This model is based on the wrinkling criterion developed by Cao and Boyce (1997) for predicting the buckling behavior of sheet metal under normal constraint.
