摘要
从裂纹技术的需要出发，对几何不对称试件进行了启裂前应力状态变化的光弹性实验力学研究，观察有切口试件的应力场变化情况，结果表明。
In order to meet the requirement of crack-technique, photoelastic method of experimental-dy- namics is employed to investigate the variation of stress of the samples which are geometrically unsymmet- rical before they commence crack. Besides, the variation of the stress within samples with notch is ob- served also. It is shown that the samples' stress is symmetrical at large when they are under the loading before they start to crack.
