In recent years, the breakdowns of piping have occurred by the stress corrosion cracking in the nuclear power generation plant. To avoid serious accident, some plants did not work during several years. The stress corrosion cracking is caused by interaction of the stress and erosive environment. This study is done about the stress corrosion cracking in the combination of the SCM435 steel and the boric acid solution. This combination has the feature that corrosion happens comparatively easily. The moving finite element analyses are operated according to acquired data by the experiment. The stress intensity factor is compared with an analytical solution, and the validity of this simulation is verified. Moreover, the application of the simulation including holes is discussed based on numerical result.
