Understanding the effects of corrosion damage, its influence on environmentally assisted crack propagation and resulting failure is of huge interest for estimating behavior of structural components in several engineering applications. In this presentation, we discuss a recently developed meshless approach for modeling corrosion damage and crack propagation 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 resulting 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 development of the peridynamics theory for corrosion damage and illustrate its working for corrosion induced crack nucleation and growth in metals.
