stress-induced growth

The accurate calculation of stress field based on EHL theory and theory of elasticity showed that the shear stresses at surface in direction of 30 ° with rolling direction cause the pitting cracks and the tensile stresses accelerate the crack growth.

结果表明：预加拉应力使裂纹起源于表面的点蚀寿命缩短，与滚动方向成30°角的剪应力是引起点蚀的决定应力。

A distribution of the traverse residual stresses perpendicular to the direction of crack growth in the compact tension ( CY) specimen has been measured by stress relaxation technique and the calculating formulas have also been derived.

本文采用应力松驰法测定了紧凑拉伸试样中，垂直于裂纹扩展方向的横向焊接残余应力的分布，并导出了计算公式。
