Abstract
Abstract The change laws of stress distribution of high strength steel wire because of the existence of the corrosion were analyzed. Study of the effects of the geometric parameters (including the depth, shape, cleaz spacing of the pit, steel wire diameter after general corrosion) of the corrosion pit on the yield load of the rusty wire were performed. It is discovered that exponential relation exists between the ratio for the depth of pit and diameter of wire and the ratio of yield load for real and theoretical, the obvious bending effect in the wire is also appeazed when the depth is large. The spacing of the pits has the very tremendous influence on yield load similazly, while the influence of shape is relative small. The stress concentration nearby the pit has created the mechanical properties of the wire obvious degeneration.
