| 摘 要： | 本文根据Okubo的各向异性分析,对纤维增强光弹性复合材料制成的对径受压圆盘进行了研究,在此基础上提出了采用一个对径受压圆盘测定光弹性复合材料三个条纹值(f_L、f_T、f_(LT))的方法。经与由三根光弹性复合材料直条试样测定的相应材料条纹值数据比较,发现现在提出的方法更为简便、可靠。

| Abstract: | According to the anisotropic analysis by H.Okubo,the stress distribution in a circular disk maked of fiber-reinforced photoelastic composite under diametrical compression is investigated.Based on this analysis,a method to measure the three independent material fringe values,fL,fT and fLT,by employing a single calibration specimen in the form of a circular disk compressed diametrically is presented.It has been found that the method presented in this paper is simpler and more valid as compared with data of material fringe values provided by three pieces of tensile-test specimen of photoelastic composite. |
