Three-dimensional modeling of in-ground cathodic protection systems with deforming anodes

Abstract The design of sacrificial cathodic protection (CP) systems conventionally involves steady-state assumptions, which means design parameters are considered constant during the in-service life of CP systems. In contrast, it is evident by experimental observations (including field measurements)...
