Abstract Scope |
We present a multiscale framework to model the nucleation, propagation and growth of twins in Mg and Mg alloys. This framework integrates three open-source computational tools developed at the PRISMS Center: PRISMS-PF, a phase-field modeling framework, PRISMS-Plasticity, a Crystal Plasticity Finite Element (CPFE) framework and CASM, a Cluster Approach to Statistical Mechanics framework. A method for twin nucleation and the dynamics for twin growth are implemented in PRISMS-PF. Concurrently, PRISMS-Plasticity calculates the effect of plastic slip as well as stress and strain fields which are required by the phase-field simulation. Additionally, thermodynamic and kinetic parameters for Mg and Mg alloys required for the phase-field model are calculated using CASM. Finally, we discuss experimental in-situ EBSD measurements of the effects of alloying on twin formation that are used to guide and validate the integrated simulation framework. |
