复合材料层合梁的弯曲与振动

Bending and Vibration of Composite Laminated Beams

本文在铁摩梓柯梁理论的基础上,应用迭合刚度的方法和Hamilton原理,导出了适合于层合梁静力分析和动力分析的控制方程及边界条件.文中应用此理论求解了层合梁在均布载荷作用下的弯曲和自由振动问题.

Based on Timoshenko's beam theory,the governing equations andboundary conditions which apply to the static and dynamic analysis ofcomposite laminated beams are obtained by using laminated stiffness me-thod and Hamilton'sp rinciple.In this paper these governing equations andboundary Conditions are applied to solve the problems of bending andvibration of laminated beams,and the exact solutions as well as Well asthe numerical results are presented.
