摘要
针对工程中常见的连接结构中含圆孔的复合材料板,根据非均质各向异性弹性理论建立计算模型。文中的应力场是借助于仿射变换的方法通过复变应力函数得到的。按照所建立的计算模型对含有圆形孔的复合材料板进行应力分析。对不同的荷载作用情况下,以及他们对孔边应力集中系数的影响进行探讨。并对两个主方向的杨氏模量的变化对孔边应力的影响进行仿真分析。
According to the nonhomogeneous anisotropic elastic theory, a calculation model of composite material plate with circular hole in common structural connection section was developed. Based on the complex function theory, the stress field was achieved by affine transformation. Stress of composite material plate with circular hole was analyzed by the model above. The influences of different loads on hole-edge stress concentration factors were discussed. And simulation analysis was made on the influences of the Young＇s modules in the two main directions upon the hole-edge stress.
