  • •A simulation method for wrinkle is proposed.•The critical wrinkling limit curve suitable for different forming conditions are established. Wrinkling is a common defect in sheet metal forming. Different forming conditions lead to complex stress loading paths, which is the main factor that makes wrinkling difficult to control. It is of great significance to accurately predict the wrinkling phenomenon of sheet metal under different forming loads. Three kinds of typical wrinkling tests are selected in this paper, which are Yoshida buckling test (YBT), wedge tensile test and deep-drawing test for conical parts. The numerical analysis models of three typical working conditions are established by using “Buckle + Dynamic-Explicit” algorithm in ABAQUS software. The accuracy of the simulation algorithm is verified by comparison experiments. The law of the critical wrinkling stress and strain data under three working conditions is studied. The unified critical wrinkling limit curve was established by using stress ratio and strain ratio based on MATLAB software. Finally, the accuracy of the curve is verified.
