Summary:Crystal plasticity simulations are a viable tool to compliment the experimental investigations by helping to understand the deformation behavior of materials at microscopic scale. Such simulation models enable the cost and time efficient parameter optimization in complicated multiphase materials. For this reason, a coupled experimental-numerical study on the formability behavior of multiphase high energy absorbing TRIP Steel Mg-PSZ MMCs is conducted. These materials were recently developed at TU Bergakademie Freiberg and have been shown to exhibit exceptional energy absorption properties during deformation. In this research a method of modelling these multiphase materials using crystal plasticity approach is discussed. The modeling is done using a newly developed highly capable and flexible crystal plasticity based code DAMASK. Both phases undergo phase transformation during deformation. The advantages and challenges faced by this new numerical modeling approach are discussed in light of experimental observations.
