In order to analyze the anisotropic hardening behavior of metals, an off - axis torsion test by combined loading is developed. In this test, the maximum shear stress direction can be changed from 0 deg to 90 deg while the ratio of maximum and minimum principal stresses is kept at –1. With increasing angle , the yield stress of the torsional - prestrained steel decreases ; the difference between the directions of the maximum shear stress and principal shear strain increment rises to a maximum value and then decreases. It is experimentally verified that anisotropy is more severe when a smaller offset strain is used in defining the yield stress.
