摘要
本文对应用云纹干涉法测量冷挤压孔周残余应力分布作了简要的论述,并应用该技术研究了冷挤压孔周残余应力在循环应力作用下的松驰问题,还探讨了残余应力的构件疲劳过程的相互作用,最后绘出不同循环应力次数作用后残余应力高周疲劳效应的几组实验结果。
In this paper, the subject of applying Moire Interferometry to measure residual stress around extruded hole is briefly discussed. This method is used for experimental study of stress flabbiness under circulating load. The interaction between residual stress and fatigue process of structure component is also discussed. Finally, several experimental results are presented.
