| Abstract Scope |
Environmental assisted corrosion cracking is a major cause for structural damage in many engineering applications. In this work, we discuss a Peridynamic (PD) approach for physics-based modeling of corrosion damage phenomena which can be applied to model crack growth and failure due to either stress corrosion cracking (SCC) or corrosion fatigue (CF). PD approach is a reformulation of classical computational mechanics that enables modeling of crack growth problem without the need to re-mesh the domain. The presentation will focus on two aspects: (i) multiphysics aspects of corrosion damage modeling using nonlocal PD approach, (ii) demonstration of corrosion crack dynamics in surrogate aluminum alloys. The developed framework is able to capture ductile damage behavior as well crack path dynamics without the drawbacks of conventional theories.
