Abstract

Abstract

In order to realize the application of the digital image correlation method in the structural mechanics of the reactor, the non-contact full-field strain measurement technology is used to study the surface speckle treatment of large-scale thin and flexible structures, and to carry out mechanical property tests; through the non-contact full-field strain measurement system-VIC-3D test system, the full-field strain data of the test piece are obtained, and the data are verified with the measurement results of the strain gauge. The results show that the digital image correlation method (DIC) has good strain testing accuracy and wide testing range.
