Abstract

In the current paper, instead of the Oriani formulation used by Sofronis and McMeeking, a more general formulation introduced by McNabb and Foster is adopted and applied successfully to a non-symmetric hydrogen diffusion scheme. The results are compared to Sofronis and McMeeking’s and Krom et al.’s work for the hydrogen diffusion near a blunting crack tip. Results represent that the McNabb-Foster formulation produces drastically different hydrogen distribution from Oriani’s equilibrium theory in both trap and lattice sites particularly when the loading time is significantly small.
