Peridynamics uses an integral approach for representing damage and other discontinuous phenomena, including the autonomous evolution of interfaces in corrosion problems. This type of computational modeling has shown surprisingly accurate simulations of physical realities like dynamic brittle fracture, impact fragmentation, pitting corrosion, SCC. In this talk will give an account on recent progress of peridynamic modeling of corrosion processes and corrosion-induced damage, and their validation against experimental results ([1-2]). Examples include: pitting corrosion and lacy covers, pit merger, crevice corrosion, galvanic corrosion, corrosion in polycrystals, stress-dependent corrosion, and coupled corrosion-fracture. I will also discuss some recent results on fast convolution-based methods for efficiently computing peridynamic models with hundreds/thousands of pits.
