Under severe corrosive environments, materials used in industrial infrastructures can experience corrosion specific damage that assists in the propagation of cracks. Peridigm (originally created by Sandia National Laboratories) is a computational peridynamics code for multi-physics simulations and can be extended to model crack propagation and material damage due to the electrochemical corrosion process. Our simulations are performed on the Cori supercomputing cluster at the National Energy Research Scientific Computing Center (NERSC). The model accounts for both mechanical and electrochemically-induced damage. The combination of these causes corrosion and their coupling causes challenges for simulations. Experimental measurements are selected to aid in the selection of parameters, which were not previously known. Some parameters are dependent on the specific properties of the tested materials while others are simply relevant to numerical implementation. To validate the model, results are compared to experimental data provided by Fathomworks which is a contractor of the United States Navy through the Port Hueneme Division.
