含孔各向异性板的孔边应力场分析

Hole-edge Stress Field Analysis on Anisotropic Plate with Hole

根据非均质各向异性弹性理论对含机翼检修孔复合材料板进行了孔边应力分析,解决了复杂孔形的边界条件问题,得到了精确解析解。对工程应用中常见的几种荷载状况(在不同纤维方向,不同加载形式、加载方向情况下)对孔边应力集中系数的影响进行了探讨。采用有限元法进行了对比计算。

The hole-edge stress of composite material plate with wing manhole was analyzed according to the nonhomogeneous anisotropic elastic theory, which resolved boundary condition problems of complex holes, got accurate analytic solution, And common state of load in engineering application and stress concentration coefficient of the hole-edge were discussed. The discussion topics also involved the arrangement and orientation of fiber,loading form and direction, etc. Moreover, computation was carried out by FEM as contrast.
