Filed: 1982-01-14
Abstract: PURPOSE:To make the quantitative evaluation of sensitivity to stress corrosion cracking possible by making use of the fact that the quantity of strain decreases when stress corrosion cracking arises in a test body which is kept applied with static strain and measuring the change in the strain when said cracking arises. CONSTITUTION:When a test body 1 is placed on jigs 2, and is applied with bending load by means of a pressing jig 3, the surface on the outside circumferential side is held in a specified static strain state.
