Multiaxial ductile fracture criteria coupled with non-quadratic non-prismatic yield surface in the predictions for a naturally aged aluminium alloy

Popis výsledku v původním jazyce

The ductile fracture has been one of the most important topics in various branches, such as the automotive, maritime or energy industry. Many approaches have been developed under certain assumptions. The present work focuses on bringing together the microstructural- and phenomenological-based ductile fracture modelling under large plastic deformations, room temperature and quasi-static monotonic loading. The complex yield criterion dependent on three stress invariants with a deviatoric associated flow rule was coupled with several advanced multiaxial ductile fracture criteria. The models were calibrated for the 2024-T351 aluminium alloy and implemented within the commercial explicit finite element code of Abaqus. Two additional tests, which were not covered within the calibration procedure, were simulated to demonstrate good predictability of the onset of cracking and its propagation, modelled by the element deletion technique. It was a small punch test and a three-point bending test of a randomly notched bar.
