| Abstract Scope |
The PRISMS Center is creating and disseminating a framework for integrating simulation, theory and experiments to accelerate predictive materials science. This talk will review the progress of the PRISMS Center faculty, staff and students in use of this framework for characterizing alloying effects on twinning and slip in Mg alloys during monotonic and cyclic deformation. A central component of the PRISMS framework is a suite of high performance, open-source integrated multi-scale computational tools for predicting microstructural evolution and mechanical behavior of structural metals. Using this software coupled with advanced experiments, including in-situ HEDM and EBSD, we have quantified alloying effects on twinning, detwinning, the propensity for <c+a> slip and grain boundary effects on slip transfer and GND formation. Experimental and simulation results are made available to the community for use and re-use via the Materials Commons, an information repository and collaboration platform that is another important element of the framework. |
