The prediction of plastic deformation of metals has been an important research topic for decades, which primarily reduces to the question of properly understanding the motions of dislocations as the major cause of plastic flows in metals. Significant progress has been made of late to accurately address the generation, evolution and propagation of dislocations in crystalline materials. Field Dislocation Mechanics (FDM) is a new plasticity theory which has been successfully implemented in a numerical framework which has been used to show the versatility of the approach in solving physically relevant practical problems not possible otherwise.
The research will focus on extending the theory to incorporate twinning deformation in single and polycrystalline magnesium alloys. Component response under cyclic loading states will be studied experimentally and numerically to prove the robustness of the modelling approach. It is expected that the research will be used to predict the structural integrity of biocompatible orthopaedic implants.
