耐久性试验中的条带判读方法

Methods for Strip-Band Identification in Durability Test

随着飞机结构耐久性设计技术的发展,耐久性试验也随之发展起来。耐久性试验所关心的是小裂纹的问题,而如何判读小裂纹却是一个辣手的问题。本文对单孔试件和传递载荷试件在耐久性试验中的条带判读方法进行了探讨,并在此基础上提出一些新的试验方法。

Research on the durability test is being carried out along with the development of the durability design technology in aircraft structures.Particular attention is given to the small crack in the test,but it is difficult to determine the size of the crack.In this paper an investigntion on the stripbank identification method for determining the size of the crack in the test of single-hole specimens and load bearing specimens is made.Some methods of strip- bank identification based on the inverstigntion in the paper are presented.
