加工硬化の方向性(第5報) : せん断応力により塑性変形した材料のせん断応力に対する方向性 その2

If it is assumed that the plastic deformation is independent of the hydrostatic stress, the state of stress in the closed thin-walled tube under internal pressure is equivalent to that of pure shear. Another state of stress of pure shear is obtained in torsion of thin-walled tube. Using these two states of stresses, the authors obtained the shearing stress-strain curves of the metals which had been deformd plastically by shear in other direction. The main object of these experiments was to study some anisotropic behaviour for shear of the metals prestrained by shear. It has been found that the conclusions reached in the previons researches by the authors on the same theme as this paper are also reliable under the conditions of stress described here, and some conclusions, moreover, on the properties of work-hardening of metals have been obtained.
