The fracture model was separately calibrated with the uniaxial tension and bulge tests to investigate the effect of the test type on the fracture prediction. It was noticed that the prediction performance was noticeably increased when the damage indicator obtained from the bulge test was employed in the numerical simulations. Moreover, the crack initiation location and its propagation path could be accurately estimated. © 2024 The Authors. Published by ELSEVIER B.V.

Tearing is one of the failure modes observed in the cup drawing process and causes material loss. This failure mode is directly related to the tool geometry, material properties and the selected process parameters.
