Hydrogen embrittlement and grain boundary fracture
TLDR
In this paper, the relationship between intergranular and transgranular fracture modes of hydrogen embrittlement is described. Butterworth et al. showed that the intergranularity fracture is observed when the hydrogen distribution is enhanced at the tip of a notch because either that is the point at which hydrogen enters from the gas phase or concentrates from the solid solution due to the stress field.About:

A continuum model for void nucleation by inclusion debonding
TL;DR: In this article, a boundary value problem simulating a periodic array of rigid spherical inclusions in an isotropically hardening elastic-viscoplastic matrix is analyzed and the effect of the triaxiality of the imposed stress state on nucleation is studied and the numerical results are related to the description of void nucleation within a phenomenological constitutive framework.

Hydrogen-enhanced localized plasticity—a mechanism for hydrogen-related fracture
TL;DR: In this article, a theory of hydrogen shielding of the interaction of dislocations with elastic stress centres is outlined, which can account for the observed hydrogen-enhanced dislocation mobility.
