Abstract
Large scale changes in geometry due to corrosion of polycrystalline pure copper are modeled using the Boundary Element Method. Axi symmetric geometries are considered. A quasi-static analysis is performed and a nonlinear polarization curve is determined from experiments to impose third kind boundary conditions. Super-elements, based on a cubic spline fit interpolation, are introduced to model the motion of the boundaries. Faraday's law is used to relate boundary motion to the surface flux. 1 Introduction Large scale changes in geometry due to corrosion of poly- crystalline pure copper is modeled using the BEM To characterize the behavior, large plate axisymmetric samples are tested, where measurements of geometrical changes vs. time are correlated to measured current density
