In order to know the structural characteristics of concrete structures, cracks generated into the concrete structure are important survey items. If one can accurately predict the cracking behavior, it is possible to contribute significantly to the cracking control technology. In this study, compression tests are performed using a gypsum plaster board having a circular hole, a crack and two cracks. And then their influences for crack generation and progression have been investigated. The measurement method was used for high-speed camera and digital image correlation.
