Authors Abstract
Content
Damage-based finite element simulations of notched tensile specimens of Al-Mg alloy AA5182 sheet were performed to select an appropriate void nucleation model and its parameters. Upper and lower bound damage-based constitutive models are used as the actual material behavior and nucleation parameter lies within these limits. Simple and complex nucleation models are compared to the experimental results and an appropriate model suggested. The lower-bound yield criterion of Sun and Wang [1] with a modified stress-controlled nucleation rule was found to give strong agreement with the experimental observations.
