Abstract
This paper presents a review of recent experimental evidence and simulation results enumerating the development of the hydrogen-enhanced localized plasticity (HELP) mechanism as a viable hydrogen embrittlement mechanism for structural materials. A wide range of structural materials, including ferritic, martensitic, and austenitic steels, iron, and nickel, are covered by the studies reviewed here, as are a variety of mechanical loading conditions and hydrogen charging conditions, supporting the concept that, despite differences in failure mode, there is a universality to the HELP mechanism.Citation
