Abstract
In high strength steels, it is indicated that hydrogen concentrates at the site of maximum hydrostatic stress. In this study, the hydrogen embrittlement test using hydrogen charged specimen was conducted. In this experiment, the different hydrogen embrittlement behaviors dependent on the applied stress wave form were observed. To investigate the effect of stress wave form on hydrogen embrittlement behavior, the analyses of hydrogen diffusion were conducted under cyclic loading conditions by using FEM and FDM coupled method. The relationship between fracture behavior by hydrogen embrittlement and hydrogen concentration was obtained.
