Abstract
Cast aluminum alloys are increasingly being used in key parts of automobiles. Establishing a failure model that is suitable for aluminum alloy castings is vital for vehicle collision simulation and damage analysis. This article determines the damage parameters of an A356 aluminum alloy under different stress triaxialities using a modified Mohr–Coulomb fracture model. It also introduces a GISSMO nonlinear cumulative damage failure model for vehicle collision analysis. The results of the study confirm that the established model can accurately reflect the failure and fracture behavior of the A356 aluminum alloy. Furthermore, when paired with wheel hub collision test results, the model demonstrates high accuracy and reliability in predicting the failure and crack propagation behavior of the A356 aluminum alloy.
