| 摘 要： | 本文对复合材料的孔边应力进行了理论计算与测试研究。文中引用了正交各向异性单向板圆孔边应力集中系数的理论计算式。介绍了用光弹贴片法对拉伸时圆孔边应刀集中系数的实测．测试值中考虑了贴片的增强效应与泊松比失配影响。最后对测试值与理论值进行了比较，符合较好。

| Abstract: | In this paper,the theoretical calculation and experimental research have been ca-rried out about the hole edge stress for composite materials. The theoretical formulas for thehole edge coefficent of stress concentration in the orthotropic single plate are introduced inthe paper.The experiment of the hole edge coefficent of stress concentration by photoelasticcoating is introduced as well.Both the reinforcing effect of the coating and the effect of pois-son ratio mismatch are considered in the measurements.The experiment result agrees wellwith the thenretical value. |
