In order to simulate hydrogen loading and discharging cycles in 3D structures under mechanically loaded services, an analytical approximation of the differential hydrogen trapping equation is proposed, as a generalization of the equilibrium Oriani’s relationship.

This solution is implemented in the Abaqus finite element software, and validated by comparison with the one-dimensional kinetic MRE code HIIPC. This model is then used on a 3D structure submitted to both hydrogen and mechanical boundary conditions.
