| Abstract: | Based on the non-equilibrium thermodynamics and the basicbalance laws of the non-linear fracture mechanics, the authors obtainthe stress corrosion cracking criterion, crack propagation rate equationand the condition of non-stationary state.In addition, the authors discussthe process of solution concentrations affecting the stress corrosion crackpropagation, which examined by the slow strain rate tensile test. |
