| 摘 要： | 本文利用干涉性非常好的激光斜入射光测弹性法,对玻璃纤维增强环氧树脂复合材料成形时,所生成的复合材料纤维界面近傍的残留主应力进行观测和解析,并分别获得主应力δ_1和δ_2。其精度在数N/mm～2的范围时,可达±0.014N/mm～2的良好程度。另外,就形状比较简单的试样,对本方法测试的结果与数值解析法的结果进行了比较。两方法的结果比较一致,证明本论文提出的方法是有效的。

| Abstract: | The paper presents a separative measurement of internal principal stress components by means of a laser photoelastic method. It has been shown that precise measurement of the principal stress is possible in heterogeneous materials and the method presented is successful for obtaining the internal thermal residual stress components in composite materials. |
