A large number of contemporary studies about hydrogen embrittlement confirmed the multiple effects of hydrogen and activity of the different hydrogen embrittlement mechanisms in low carbon steels. However, critical evaluation and quantification of the synergy between the hydrogen-enhanced localized plasticity (HELP) and decohesion-based (HEDE) mechanisms, and their combined effect on macromechanical properties, still does not exist. This paper focuses on a structural integrity models for hydrogen embrittlement of low carbon St.20 (AISI 1020) steel in the presence of simultaneously active hydrogen embrittlement micro-mechanisms.

A background for the analysis of the viable hydrogen embrittlement mechanisms: hydrogen-enhanced localized plasticity (HELP) and hydrogen-enhanced decohesion (HEDE) in a ferritic-pearlitic carbon steel and development of a model for structural integrity analysis is a literature overview about the current state of the art in hydrogen embrittlement modeling and studies (140 References), presented in this paper.
