Evaluation of crack-growth rate under conditions of simultaneous action of static loading and corrosive media

Materials Science Aims and scope

Abstract

We construct a numerical model of subcritical growth of cracks in metals subjected to the simultaneous action of loading and corrosive hydrogen-containing media. The model is based on the hypothesis that hydrogen plays the predominant role, that under the conditions of stress corrosion, the process of crack growth passes through two stages, and on the deformation criterion of fracture. The crack-growth rate was determined as a function of the crack tip opening displacement δ, its critical value δc, standard electrode potential of the metalE 0, and pH value of the medium. The reliability of the model under consideration is corroborated by experimental results.
