Phase-field modeling of damage in aluminum alloy

Abstract

Phase-Field Damage Model (PFDM) is a cutting-edge simulation tool for prediction of damage and crack evolution in materials. This paper shows simulation of AA5083-H321 ductile behavior using the modified PFDM coupled with a von Mises metal plasticity model. Uniaxial tensile tests at room temperature were performed on AA5083-H321 flat specimens in order to identify material parameters for numerical simulation and to verify the modified PFDM implemented into in-house software PAK. Comparison of the obtained results showed good agreement between experimental and simulation force-displacement responses.
