A paper on the "surface mobility mechanism" (SMM) of SCC was based on "abnormally high" surface diffusivity influenced by stress in the crack tip, which was proposed by J.R. Galvele in 1987 and later criticized by K. Sieradzki and F.J. Friedersdorf in 1994. However, the author continued to promote his concept in recent papers, which was an incentive of the present analysis. The tests carried out by the author of SMM could not be accepted as experimental proof of the SMM. A critique of this paper was presented.
- Effects of strain
- Stress corrosion
