Stress Corrosion Cracking

Stress corrosion cracking is a common failure mode for steels and other high strength alloys in corrosive environments. The aim of this research is to understand underlying physical mechanisms of stress corrosion cracking in steels and develop multiscale computational framework by incorporating these physical mechanisms for better predictions.
