The Mechanical Performance Degradation of Steels Effected by Corrosion

Abstract:

Corrosion of the steel affects seriously its mechanical performance. Based on the finite element methods, strength tensile properties of corroded steel were studied. Pit shapes and pit depths, pit locations, etc on the mechanical behavior of steel were studied mainly. Pit depth is major cause of produce rust steel mechanical performance degradation, because there is an obvious stress concentration phenomenon around pit, cause steel mechanics performance degraded significantly. Pit shapes and lengths may also be affected steel mechanical properties.
