Influence of surface texture and residual stresses on fatigue strength of wire rope

Influence of surface texture and residual stresses on fatigue strength of wire rope

$15.00

This paper presents the results of investigations into the fatigue strength of wire rope (zinc-coated and uncoated) for three steel grades: D55, D65, and D80. Residual stress and some parameters of the surface texture in longitudinal and circumferential direction were also determined. It has been proven that the hot zinc coating process lowers the fatigue strength of wire rope. This paper proposes a quantitative method for the estimation of the residual stresses, surface roughness, and material properties on the fatigue strength of the tested wire.
