Dynamic Response of Laminated orthotropic Spherical ShellsIncluding Transverse Shear Deformation and Rotatory Inertia
【摘要】 本文建立了计及横向剪切变形和旋转惯性的复合材料轴对称层合圆柱正交异性球壳的运动方程.在此基础上,用有限差分法计算了球壳在轴对称动力载荷下的动态响应,并讨论了材料参数、结构参数和横向剪切变形的影响.
【Abstract】 In this paper,the equations of motion of axisymmetrically laminated cyclindrical orthotropic spherical shells are derived.The effects of transverse sheardeformation and rotatory inertia are considered.On this basis,the dynamic response of spherical shells under axisymme trie dynamic load is calculated by usingthe finite differnce method.The effects of material parameters,structralparameters and transverse shear deformation are discussed.
