| Abstract: | Abstract: A constitutive materials model, which includes Ohno–Wang's kinematic hardening rule, is employed to simulate the isothermal monotonic and cyclic behaviours of high‐pressure die cast magnesium AM60B alloy under uniaxial loading condition. An implicit constitutive stress integration scheme developed by Kobayashi and Ohno 9 is used to code the model into an ABAQUS user materials subroutine (UMAT). After the material parameters used in the current model were obtained from the experimental results, the predictive capability of the model was verified. |
