Corrosion Product Film-Induced Stress Facilitates Stress Corrosion Cracking [PDF]
Scientific Reports, 2015 AbstractFinite element analyses were conducted to clarify the role of corrosion product films (CPFs) in stress corrosion cracking (SCC). Flat and U-shaped edge-notched specimens were investigated in terms of the CPF-induced stress in the metallic substrate and the stress in the CPF. For a U-shaped edge-notched specimen, the stress field in front of the
