In this study, it is aimed to establish a quantitative correlation of material microstructure with its mechanical deformation properties by using crystal plasticity model coupled with representative volume elements for a bcc steel sheet. Anisotropic plasticity as one of the most important mechanical properties has been focused on. In addition, the strain rate dependence of the flow behavior is also highlighted in the study. Parameter calibration method for the strain rate sensitivity parameter is demonstrated. With the constructed representative volume elements model and the calibrated crystal plasticity model, the prediction of the stress-strain responses for different loading directions and rates are compared with the experiments. It is concluded that the employed method for the microstructure model construction and parameter calibration shows good performance for the plastic anisotropy and strain rate sensitivity description.
