残余应力测定的基本知识——第七讲 机械法测残余应力

BASIC KNOWLEDGE OF RESIDUAL STRESS DETERMINATION——LECTURE No.7 RESIDUAL STRESS DETERMINATION BY MECHANICAL METHOD

机械法是测残余应力的一类方法,其中常用的有盲孔法、环芯法和剖分法。国内外还制订了盲孔法和环芯法测残余应力的行业标准。介绍了上述三种方法的基本原理及需要注意的几个问题。

Mechanical method is a category of measuring residual stress.In the category,hole-drilling method,ring-core method and dissecting method are commonly used.China and some other countries have formulated industry standard of measuring residual stress by using hole-drilling method and ring-core method.The basic knowledge and several points need to notice are introduced.
