Abstract
An uncoupled ductile fracture model, based on Mu–Zang model, is extended by incorporating a hydrostatic stress term. An aluminum alloy material (Al 6016-T6) is selected with a series of static ductile fracture tests performed on four different specimens, which can cover a wide range of stress states. A robust simulation-experiment approach is adopted to characterize the correlation between the material’s ductility and distinct stress states. The extended model is then calibrated using least-squares optimization. The resulting 3D fracture surface demonstrates acceptable deviations from the tested data, manifesting a promising capability of the extended model to describe the ductility of the considered material within a wide stress state range. In addition, the comparison against other representative ductile fracture models further confirms a good prediction performance of the model proposed.
