Abstract
An open-source parallel 3-D crystal plasticity finite element (CPFE) software package, PRISMS-Plasticity, is presented here as part of an overarching PRISMS Center integrated framework. A new rate-dependent twinning-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. The model is validated versus high energy diffraction microscopy (HEDM) results of Mg alloys during cyclic loadings. PRISMS-Plasticity TM is another feature which has been developed as a new open-source rapid texture evolution analysis pipeline based on the Taylor model, which is integrated into the open-source crystal plasticity software, PRISMS-Plasticity. The developed framework is used to capture the effects of alloying on texture development in Mg–Zn–Ca alloys. Finally, the PRISMS-Plasticity software has been integrated with the PRISMS-PF phase-field framework to model twinning within Mg alloys.KeywordsMagnesiumICMEModelingSimulation
