三类内应力之间的关系及其对疲劳的作用
Relationship of Three Types of Internal Stresses and Their Effects on Fatigue
摘 要
系统阐述了三类内应力的分类和内在关系，指出除了业内熟知的残余应力外，微观应力尤其是第二类内应力亦具有重要的工程应用价值，并给出了第二类内应力可能的测试手段——聚焦离子束（FIB）微创法，最后分别对三类内应力对材料疲劳性能的影响及作用进行了详细的分析和阐述。

Abstract
The classification and internal relations of the three types of internal stresses were systematically described. It is pointed out that in addition to the well-known residual stresses in the industry, the microscopic stress, especially the second type of internal stress, also has important engineering application value. A possible method-the focused ion beam (FIB) minimally invasive method for measuring the second type of internal stress was given. Finally, the effects of the three types of internal stresses on the fatigue properties of the materials were analyzed and elaborated in detail.
