The retardation of tensile overload will reduce the 321SS crack growth speed for the furcation on the fracture section.
拉伸超载能阻滞321不锈钢的疲劳裂纹扩展速率，样品断面有明显的周期性的裂纹偏折或分叉；
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。
In this model, the plastic zone induced by the overload is affected by the three-dimensional constraints, and it leads to significant influence on the crack closure and growth rate.
在此模型中，裂尖的三维约束状态显著影响超载塑性区，从而显著影响裂纹的闭合和扩展速率。
The fatigue fracture surface exhibits obviously impact facture characterization, when the crack propagates into overload tensile zone.
当裂纹扩展至拉伸过载区，断口表面则呈现明显的冲击断裂特征。
