From the experimental facts reported in Part 1,the author anticipated that if the metals previously over-strained by shear in one direction are tested by shear in various directions, some properties of anisotropy produced by plastic deformation will be more evident than the results of the experiments in Part 1. When a thin-walled tube is subjected to the combined loading of external hydraulic pressure and axial tension, if the absolute value of circumferential stress equals to axial stress, the tube is under the pure shear in the direction of 45 degrees to its axis. Using this stress-condition and the stress-condition of torsion the author tested the anisotropic properties for shear of the metals over-strained by shear. The results of these tests confirmed the author's anticipation, and made his idea as to anisotropy of work-hardened metals more reliable.
