Description

Recently it has been discovered that the machining process has done a great influence over the occurrence of stress corrosion cracking condition of the austenitic stainless steels. The residual stress and plastic strain of the machined surface has been thought to be the cause of SCC. In order to clarity this problem, we carried out the machining simulation for processing the work material by the finite element analysis and examined the equivalent plastic strain compared to the hardness of machined surface layer of work material.
