摘要：

This study presents a unified method to model electrodeposition and galvanic corrosion. The governing equations and boundary conditions are recast in their nonlocal form by using the peridynamic differential operator. Electric potential and mass transport equations are solved simultaneously in ANSYS through implicit algorithms for computational efficiency and complex geometry. Deposition and corrosion fronts are established by applying the concept of deposition fraction and examining the concentration values. Element matrices associated with peridynamic interactions are constructed through MATRIX27 elements native to ANSYS. The damping is modeled using combin14 element and the resulting equations are solved in an implicit fashion. Accuracy of this unified method is established by comparison with the published experimental measurements and simulations concerning simple and irregular geometries.(c) 2023 Elsevier B.V.
