摘要
本文针对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。按照所建立的数学模型对含有圆形孔的复合材料板进行应力分析。不同荷载作用对孔边应力集中系数的影响进行探讨,并就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 the composite material plate with the circular hole in joint structures is set up. The stress field is achieved by affine transformation through the complex function theory. The stress is analyzed in the composite material plate with circular hole by the model above. The influence on hole-edge stress concentration factors of different loads is explored. And simulation analysis is made on the influence of Young＇ s modules in the two main directions on the hole-edge stress.
