Recent Advances in PRISMS-Plasticity Software for Simulation of Deformation in Mg Alloys

An open-source parallel 3D crystal plasticity finite elementCrystal Plasticity Finite Element (CPFE) software package, PRISMS-PlasticityPRISMS-Plasticity, is presented here as a part of the overarching PRISMS Center integrated framework. A new PRISMS-Plasticity indentation module is integrated into the framework which can efficiently model indentation of large microstructuresMicrostructure of Mg alloysMagnesium alloys (Mg alloys). A new rate-dependent twinningTwinning-detwinning model is incorporated into the framework based on an integration point sensitive scheme to model Mg alloys. The model includes both kinematic and isotropic hardening in order to handle cyclic response of structural metals. PRISMS-PlasticityPRISMS-Plasticity TM is incorporated to rapidly simulate the effects of alloying on textureTexture development in Mg-Zn-Ca alloys. Finally, the PRISMS-Plasticity software has been integrated with the PRISMS-PF phase-field framework to model twinningTwinning within Mg alloysMagnesium alloys (Mg alloys).
