PRISMS-Plasticity: Recent Advancements for Simulating Deformation of Mg Alloys

Abstract

Mg alloys, as lightweight structural materials, can significantly reduce the weight of transportation systems and consequently impact both fuel economy and air pollution [1]. Integrated Computational Materials Engineering (ICME) of Mg alloys has significantly advanced during recent years. An integral part of every ICME framework to design Mg alloys is a tool to model the mechanical response including stress–strain, twinning, cyclic loading, fatigue, deformation mechanisms, etc. Crystal plasticity is a powerful tool which can capture many of the mechanical responses in Mg alloys [2]. An open-source parallel 3-D crystal plasticity finite element (CPFE) software package PRISMS-Plasticity has been developed as an integral part of the PRISMS center and is freely available via GitHub [3]. PRISMS-Plasticity has a wide range of features, and its parallel performance demonstrates that it scales exceptionally well for large problems running on hundreds of processors. Systematic workflows have been established for inputting 2D and 3D microstructures and texture information, including pipelines for Dream3D. Online tutorials, documentations, and training workshops are available for PRISMS-Plasticity.
