摘要
针对含有椭圆孔无限大对称复合材料层板在弯曲载荷作用下的应力集中问题,利用经典的复合材料层板理论,将对称层板弯曲归结为均匀各项异性薄板弯曲问题来求解,采用各向异性薄板弯曲理论中复势方法,以保角映射技术为工具,得到了其解析解。并详细讨论了椭圆孔或圆孔对单层板和对称层板弯曲应力集中的影响,得到了对工程应用有一定价值的结论。
To solve the stress concentration problem of infinite symmetric composite laminates with elliptical holes under bending; based on classical composite laminates theory, resolute symmetric laminates to uniform anisotropic plate problem, via using complex potential means of it as well as conformal mapping, analytic solution find. Refining discussing various cases of single along with symmetric composite laminates by the effect of elliptical or circle holes, obtain several essential conclusions to engineering application.
