Abstract Scope |
Given the importance of twinning as one of the main deformation modes in magnesium alloys, a clear understanding of the mechanisms involved in twin nucleation, propagation, growth, and transmission is needed for the design of Mg alloys with improved mechanical properties. We introduce a new open-source framework, PRISMS-MultiPhysics, in which phase-field and crystal-plasticity models are concurrently coupled to capture the morphological evolution of twins. We describe the implementation of the governing and constitutive equations and demonstrate the application of the framework to the simulation of twinning-detwinning in Mg. In addition, we discuss plans to focus on solute effects, in particular for the Mg-Zn-Ca alloy system. Finally, we discuss plans to further integrate the framework with the Cluster Approach to Statistical Mechanics (CASM) tool to facilitate accurate parameterization of PRISMS-MultiPhysics with thermodynamic and kinetic data derived from atomistic calculations. |
