Abstract:	The general wrinkling theory based on the rate formulation of the principle of virtual work has been applied in a number of studies on wrinkling during sheet metal forming. No contact with the die was allowed. In this study it is shown that with the right choice of wrinkling modes, the theory can also be used for contact situations. Furthermore, loads normal to the sheet can be taken into account. Therefore, the wrinkling theory has a larger area of application then it was previously considered
