Abstract
To study the stress corrosion characteristics of wire with different wear conditions, namely depth, cross angle and length, Finite Element (FE) models of worn wires are developed based on multi-physics coupling analysis. The electromechanical parameters required for the FE simulations are determined from experimental testing. Then, the stress corrosion characteristics, i.e. stress, corrosion voltage, and corrosion current density, of the wear surface under different tensile displacements are obtained. The results show that the stress increases uniformly under different tensile displacements. However, different wear states present different stress corrosion characteristics. When the tensile displacement or wear state is sufficient to cause plastic deformation of worn wire, the corrosion characteristics changes dramatically.
