Evaluation of ductile failure models in Sheet Metal Forming

Evaluation of ductile failure models in Sheet Metal Forming

Traditionally, combination of equivalent plastic strain and stress triaxiality parameters are taken into account when performing characterization of material ductility. Some well-established models like Lemaitre model, GTN based models and many others perform relatively well at high-triaxiality stre...
