A three-dimensional multiscale model of intergranular hydrogen-assisted cracking [PDF]

open access: yes, 2010
We present a three-dimensional model of intergranular hydrogen-embrittlement (HE) that accounts for: (i) the degradation of grain-boundary strength that arises from hydrogen coverage; (ii) grain-boundary diffusion of hydrogen; and (iii) a continuum model
