Anisotropy-corrected MTS constitutive strength modeling in HY-100 steel

A Taylor factor normalization routine was developed for Mechanical Threshold Strength (MTS) predictions of stress-strain response. Polycrystal plasticity calculations were used to predict Taylor factor evolution during the deformation event. For the case of a HY-100 steel compression test at 77K, the method resulted in a significant improvement in predicted response.
