| 摘 要： | 本文提出了一种用于光弹性复合材料的简化应变——光学定律。按照这一简化定律。模型材料的主应变差和主应变方向只要利用光弹性实验测出的等差线与等倾线即可求得。些是一种正交异性光弹性分析的近似方法,这一方法所得结果与实验数据比较,最大误差在10％左右。由于采用简化应变——光学定律使得正交异性光弹性分析工作大为简便,因此它是一种适合于工程应用的近似方法。

| Abstract: | A simplified strain-optic law for photoelastic composites is being propoced in this paper. According to this law the difference and direction of major principal strain of orthotropic model moterials can be obtained from only two photoelastic measurements (isochromatie-fringe order and isoclinic angle). This is an approximate method for orthotropic photoelastic analysis. The maximum error between the experimental results and the predictions of the approximate method is approaching to 10 percent. By using this law the orthotropic photoelastic anylysis is easier to make. Therefore the method is practical for engineering utilization. |
