“…Some researchers utilize the surface strain of specimens as the failure strain to establish fracture failure models. Liu et al [ 19 ] combined the modified Bressan–Williams–Hill local instability criterion with the damage evolution model to propose a material failure criterion for numerical analysis of the fracture behavior of aluminum alloy plates. Gu and Mohr [ 20 ] developed an anisotropic form of the Hosford–Coulomb fracture criterion to accurately depict the anisotropic fracture behavior of AA6260–T6.…”

This study investigated the deformation responses and fracture behaviors of AA6061 under different stress triaxiality. Specimens of specific shapes and sizes were designed to achieve different stress triaxialities. Mechanical experiments and scanning electron microscopy analyses were performed to capture the mechanical behaviors and failure features of each specimen. Results showed that thicker specimens deformed more evenly in thickness than thinner specimens but exhibited slightly more brittleness, while the opposite was true for the notch radius of the specimens. Therefore, these two factors could be applied to the design of specimens for specific testing requirements. The failure mechanism was sensitive to the geometrical factors of the specimen. In addition, the distribution of failure features on the fracture surface was found to play a dominant role in the change in mechanism.This article is protected by copyright. All rights reserved.
