摘要
采用实时观测云纹干涉法 ,测试并研究了正交异性Ⅰ型裂纹的应力强度因子。用三维云纹干涉仪和数字图像采集技术获得了清晰的反映试件裂尖附近全场位移的云纹图 ,进而推算出应力强度因子。并对贴片云纹干涉法和实时观测云纹干涉法进行比较。
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.
