In this project three unique criteria (e.g., a new material constitutive model and two damage based fracture models) were introduced for the industry usage of predicting shear fracture in stamping AHSS with FEM. Detailed procedures were developed in this study to allow the prediction of forming fractures of AHSS using commercial FEM codes. By adopting one of these failure criteria and possibly compensated FLD’s, simulations of forming operations are expected to predict shear fractures of AHSS more accurately.
