Standard of New (welding) residual stress testing come out 2009-09-07 Indentation measurement of residual stress-strain method, primarily by taking measurements around the spherical indentation of elastic-plastic strain field change information to obtain the size of the original residual stress. Regarding the subject, since the last century 1990s, especially in the past 10 years, under the Chinese Academy of Sciences Innovation Fund and other projects support and the completion of a large number of experimental and theoretical research, and through the production of the test of practice, it received wide acclaim and applications. The picture shows the newly developed KJS-3-type strain method indentation test system, the system has the advantageous of high accuracy, test process is simple, portable equipment, non-destructive and so on.
