A First Step Into Modeling Hydrogen Embrittlement with a Commercial Finite Element Program

Kurzfassung

Considering a quick set-up of numerical simulations of hydrogen embrittlement, the implementation of hydrogen embrittlement models into commercial Finite Element programs is an attractive alternative to in-house developed hydrogen embrittlement modeling codes. The purpose of this paper is to briefly discuss the first step into modeling the isothermal stationary hydrogen embrittlement through the implementation of a hydrogen embrittlement model based on the hydrogen-induced enhanced plasticity (HELP) mechanism into a commercial Finite Element program. The consistency of the proposed methodology has been assessed by the analysis of Finite Element simulation results of an isothermal stationary stressed ultrasonic HCF test sample with and without considering the influence of hydrogen.
