| Abstract: | Because of the limitation of the measure points′ counts and space by strain electrical measuring method in the static experiments of complex large launch vehicle shell structures, the digital speckle correlation method was presented. The full field strain could be obtained effectively, and the method would guide and modify the design of shell structures. |
