The phase field method is a powerful tool for studying microstructural evolution in various domains of material science, including initiation and propagation of fracture. In this work, a new formulation is developed within the phase field method for modeling stress corrosion cracking induced by anodic dissolution. The effects of both electrochemical and mechanical processes are taken into account in the new frame work. The classical phase transformation model is coupled with mechanical problem in a robust manner, providing an efficient tool to study the competition between electrochemical and mechanical impact on the fracture phenomena .
