</script>The author reported, in the first report, a method of measurement of the residual stress in the heat treated solid cylinder with small diameter, consisting of the removal of surface layer of the specimen by corrosion and the measurement of the resultant changes of the length in axial direction and the specific volume of the remaining portion. In the present report, the author shows a method of measurement of the residual stress in the heat treated hollow or solid cylinder when the inner layer of the specimen is removed.Let 0σz, 0σt and 0σr be the residual stresses in the axial circumferential and radial direction respectively, further let ez and ev be the changes of axial strain and volume strain accompanied by removal.Then the three stresses 0σz, 0σt, 0σv are expressed as follows:0σz=E/1+ν{(fb-f)d/df(ez+ν/1-2νev)-(ez+ν/1-2νev)}0σt=-E/1+ν{(fb-f)d/df(ez-1/1-2νev)-(fb+f)/2f(ez-1/1-2νev)}0σv=-E/1+νfb-f/2f(ez-1/1-2νev)where, E=Young's modulus.ν=Poission's ratio.fb=Cross sectional area in the outer diameter of cylinder.f=Removed area.The change of volume strain ev is, when we put v0 and v for the specific volume of the specimens before and after removal.ev=2(1-2ν)/3(1-ν)(v-v0)/v0The procedure and the actual data of measurement are explained. The effect of boring by cutting is also reported.
