A new implementation of the anisotropic plasticity–ductile damage model coupling Hill yield and GTN failure criteria in Abaqus UMAT: Identification of parameters for AA6022

This paper adopts a 2D implementation of an anisotropic plasticity–ductile damage model coupling Hill yield and GTN failure criteria and extends it to a 3D implementation in a user material subroutine (UMAT) of Abaqus software. The implementation is first verified via comparisons with an isotropic m...
