207In this report, the method of measurement of the residual stress quenched or tempered plate, acting symmetrically with respect to the neutral plan, is explained, which consists of the removal of the surface layer of plate from both sides by corrosion and the measurement of the resultant change of the specific volume. Let _0σ_x and _0σ_y be the resudual principal stress components acting on the cross section normal to the axes x, y in the plate, and ε_ν the resultant change of the volume strain in the remaining portion after the removal of outer layer up to thickness 2z. _0σ_x=_0σ_y=-E/2(1-2ν)(ε_ν+z(dε_ν)/(dz))ε_ν=(2(1-2ν))/(3(1-ν)) (ν^^--ν^^-_0)/(ν^^-_0) E : young's modulus,ν : Poisson's ration,ν^^-_0, ν^^- is the specific volume before and after removal of layer. The principle and the accrual data of measurement are explained.
