Fracture prediction of 5052 aluminum alloy sheet forming using machine learning-calibrated DF-2013 uncoupled ductile fracture criterion

Ductile fracture is the primary failure mode in sheet metal stamping, directly affecting material forming limits and product quality. Accurate prediction of ductile fracture is critical for optimizing stamping process parameters, avoiding crack defects and cutting production cost...
