【摘要】 本文根据 Sampson 提出的应力—光学定律,对正交各向异性复合材料带有圆孔的有限宽板进行了分析研究,得到了复合材料带有圆孔板孔边的应力分布状态.本文的实验结果与正交各向异性受拉带孔无限和有限宽板的两种关于圆孔孔边应力分布状态的理论解符合较好.更多还原

【Abstract】 Based on the stress-optic law presented by Sampson,some of limited wide plates containning a hole which is made of orthotropic composite materials with different fibre direction are analyzed by the pho- to-orthotropic-elastic technique,and the states of stress distribution on the edge of each circular hole of them are obtained.The results obtained by the test in this paper are in a better agreement with the two theoretical solutions which are obtained by calculation on the states of stress distribution on the edge of circular hole of the orthotropic limited and unlimited wide plates with a circular hole under the tension and compression,and the correctness of the theoretical solutions can be verified simultaneously更多还原
