Compressive residual stress的意思|示意

Compressive residual stress fields in the surface region of small specimens are determined.

测定了小试样表面层的残余压应力场。

The results of the analyses show that high residual compressive stress and fine scattered martensite units are the main cause of improving fatigue properties.

分析表明，高幅值的残余压应力和“有效晶粒”细化是提高弯曲疲劳性能的主要因素。

In the weld transverse residual stress near the tensile stress, also had both compressive stress;

在焊缝附近的横向残余应力既有拉应力，也有压应力；

Owing to the loss of their adjacent material constraint, the residual stress on the cutting edge of the small test block reduces, even changing from compressive stress to tensile stress.

由于失去与原有相邻材料的约束作用，小试块切割的边缘处残余应力减小，甚至由残余压应力转变为残余拉应力。

Compressive residual stress increases the crack closure effect at the notch and may lead to a non-propagating crack.

残余压应力使缺口处裂纹闭合力增大甚至可出现非扩展裂纹。

The overload effects were controlled by various factors such as crack blunting, residual compressive stress ahead of the crack tip and crack closure induced by wake zone plasticity.

过载效应是裂尖钝化、裂尖附近残余压应力和裂尖尾部塑性诱导闭合等共同作用的结果。
