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激光实验力学研究 ,观察有切口试件的应力场变化情况 .结果表明 ,试件在启裂前的应力状态基本上是对称的 ,应力无大的变化 .
Considering the requirement of crack technique, the stress condition of geometrically unsymmetric samples before crack initiation os investigated by means of experimental mechanics with laser in order to observe the variation of stress field of notched samples. The result shows that the stress condition within the samples after load applying and crack initiating is basically symmetric without large variation of stress.
