| 摘 要： | 由于各向异性材料的弹性常数随方向而变化 ,这就使通常用于各向同性材料的光弹性贴片法的基本方程失效。本文从光弹性贴片法的基本原理出发 ,给出正交各向异性板内任一点的应力计算公式 ,同时也提出了正交各向异性板厚度效应的修正系数。文中对带圆孔正交各向异性板孔边应力分布做了光贴片实验并与文献 [2 ]中的有关数值解进行了比较 ,验证了本文工作的正确性

| Abstract: | The basic eqations of photo elastic coating method can not be used to the anisotropic mateirals because their elastic constants are varied with the directions. Based on the photo elastic coating method,the calculating formulus which are used to determine any point of orthogonal anisotropic plate are given and the revised factor of coating thick is proposed.The experimental result of anisotropic plate with a hole is presented by using the photo elastic coating method and compared with Ref.3, it is shown that the method proposed here is correct. |
