宏应变和微应变的定义

[中文适用范围]： 在材料残余应力的分析和测量中，人们注意到术语“宏观应变”和“微应变”的解释经常存在差异。为了便于该领域研究人员之间的交流，这两个术语的定义由SAE疲劳设计与评估委员会提出。由于“宏观应力”通常是根据残余应力分析中的“宏观应变”计算得出的，为了保持一致，给出的定义适用于“宏观应变”和“微应变”。 [外文原描述]： In the analysis and measurement of residual stresses of materials, it has been noted that there are frequently differences in interpretation of the terms "macrostrain" and "microstrain." To assist communication among research personnel in this area, definitions for these two terms are suggested by the Fatigue Design and Evaluation Committee of SAE. Since "macrostress" is commonly computed from "macrostrain" in residual stress analysis, to be consistent, the definitions given are for "macrostrain" and "microstrain."Cross Reference:
