Plastic instabilities refer to a wide family of material nonlinearities met in several solid materials. They correspond to a heterogeneous strain response under homogeneous loading conditions, and manifest as an erratic workhardening accompanied by strain localization bands that kinetics are sensitive to temperature and loading rate, among other material properties. This phenomenon hinders the industrial use of aluminium-magnesium alloys. It involves harmful mechanical and aesthetic consequences that can hardly be predicted at the design step. Constitutive models can recreate localization bands but they fail to accurately predict their kinematics. Moreover, they are subjected to several issues such as mesh sensitivity, a high computational ...
