| Abstract: | The moire interferometry method is used to measure and study stress intensity factors of mode I crack in orthotropic composite plate. Moire is obtained by 3D Moire instrument and processing of digital image. The stress intensity factor K 1 are calculated from the crack tip displacement field. A comparison of Moire interferometry with real time observation Moire interferometry is also made. |
