  stress fatigue
This mechanism is discussed in relation to the anomalous mean stress fatigue behavior exhibited by this alloy.
      
An experimental investigation was undertaken to study the relationship between mechanical properties and low stress fatigue crack propagation.
      
The role of mechanical properties in low-stress fatigue crack propagation
      
For the composites tested in fatigue, the aged eutectic has better high-stress fatigue resistance than the as-quenched material, but for low-stress, high-cycle fatigue their cycles to failure are nearly the same.
      
Such stress fatigue is caused by the non-uniform dimensional changes that result from thermal and moisture content gradients between the surface and the bulk of the resin and from inhomogeneities and defects.

From the study of the wear behavior, the main wear mechanism of chilled cast iron tappet under boundary lubricating condition is suggested as a fatigue process. The earlier stage of the wear process is scratch characterized by shallow delamination and strain fatigue. But the later stage is pitting process, which may be characterized by stress fatigue.

作者针对冷激铸铁挺杆的磨损特性,提出了在边界润滑状态下挺杆磨损的主要机制是疲劳磨损。磨损初期是以浅层剥落形式出现的擦伤磨损,它属于应变疲劳;后期的磨损主要是点蚀磨损,它属于应力疲劳。 从材料硬度越高,擦伤倾向越大的试验结果,作者认为决定应变疲劳寿命的主导因素是裂纹扩展速率da/dN;从材料强度越高,抗点蚀能力越强的试验结果,作者认为决定应力疲劳寿命的主导因素是材料强度。

Through the fatigue experiment on CT speciment made of polycarbonate and the photoelastic experiment conducted at the same time,the writers find that residual stress field is formed in the neighborhood of crack tip along with the growth of fatigue crack,through it is the problem of low stress fatigue.The unloading residual stress field is gave corresponding to the number of cycles in the neighborhood of crack tiP. Thus the existence of close effect is revealed and its measurement criterion is put forward.The result of the experiment shows that close effect will reduce the stress intensity factor.So the original theoretical calculating formula for stress intensity factor is no longer applicable. A simple and practical revised scheme is proposed.

聚碳酸酯紧凑拉伸试件的疲劳试验和光弹性试验表明,尽管是低应力疲劳问题,但随着裂纹的扩展在裂尖附近出现残余应力场。给出了与循环周次相对应的卸载残余应力场,从而揭示出闭合效应的存在并提出其度量准则。试验表明,闭合效应使得应力强度因子降低,因此原有应力强度因子理论计算式不再适用,对此提出了一种简便有效的修正方案。
