Crack Growth Finite Element Analysis Plastic Strain Stress Corrosion Cracking
Plastic strain as a function of the distance from a growing stress corrosion crack tip is quantitatively evaluated by three-dimensional ela stic-plastic finite element analysis. The strain distribution obtained by node-release simulation of crack growth follows the logarithmic l aw. The criteria for the transition from a stationary crack to a growing crack were investigated. Results suggested that the prediction of crack growth by the FRI model, in which oxidation kinetics and continuum mechanics has been...
