Corrosion crack initiation and growth is of huge interest for estimating life of structural components in several engineering applications. Crack propagation phenomena is a result of complex interactions between electrochemical processes and stress redistribution in response to material/environment. Here, we discuss recent developments in the realm of meshless peridynamics approach for modeling corrosion damage and resulting crack propagation phenomena under synergistic effects of corrosion and mechanical loading. The approach is based on non-local peridynamics theory that replaces governing equations which are typically partial differential equations (as in classical continuum mechanics) with integro-differential equations that are easy to solve across discontinuities like crack. The framework is well suited for modeling crack propagation and failure, without the need to re-mesh the domain or the need for complicated crack path algorithms like that of XFEM or cohesive element method. Here we summarize the developments of the peridynamics approach and illustrate its capabilities.
