DUCTILE FRACTURE CRITERIA IN PREDICTION OF CHEVRON CRACKS
Kubík P., Petruška J., Hůlka J.
pages 339 - 342, full text

Seven ductile fracture criteria are applied to simulation of cold forward extrusion and their performance in prediction of chevron cracks is presented. The criteria are implemented as user material subroutine (VUMAT) into ABAQUS/Explicit code and their calibration is based on tensile testing of several types of tensile specimens. Ability of the criteria to predict material damage in forward extrusion is tested under various combinations of process parameters.
