Dislocation dynamics (DD) models have historically been purely mechanical and quasi-static. The neglect of thermomechanical effects is a significant source of error in predicting stress loading behaviour observed in high strain rate DD simulations. A two-dimensional, fully- coupled thermomechanical DD model based on the eXtended Finite Element Method (XFEM-DD) was recently developed to address thermomechanical effects by capturing heat generation of dislocation motion. Simulations using this model have qualitatively demonstrated the increased significance of thermal effects and temperature rise with increased strain rates, as well as increased accuracy in capturing stress-strain behaviour. The XFEM-DD will be refined through the inclusion of previously neglected inertial effects and the impact on the accuracy of load behaviour will be determined.
