Authors

The purpose of this work is the modeling and simulation of the deformation behavior of thin sheets consisting of large grains of Fe-3%Si and comparison with experiment. To this end, a crystal-plasticity-based finite-element model is developed for each grain, the grain morphology, and the specimen as a whole. The crystal plasticity model itself is rate-dependent and accounts for local dissipative hardening effects. In order to compare model predictions with experiment, the material parameters have been identified with the help of single-crystal data from [1-3]. Identified model predictions are compared with the experimental results of [4] for the deformation behavior of thin sheets of Fe-3%Si loaded incrementally in tension at room temperature. To this end, attention is restricted to the two slip families {1 1 0} and {1 1 2} expected to be active at room temperature. Comparison of model predictions for grain morphological evolution with the corresponding experimental results up to 19.5% deformation on this basis imply good agreement. In addition, model predictions for the development of the strain field and the grain reorientation field are discussed and evaluated.
