Research Center of Solid Mechanics, Peking University of Aeronautics and Astronautics, Beijing 100083, P. R. China

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 cylindrical orthotropic spherical shells are derived.Theeffects of transverse shear deformation and rotatory inertia are considered.On this basis,the dynamic response of spherical shells under axisymmetric dynamic load is calculated using the finite difference method The effects of material parameters.structural parameters and transverse shear dgformation are discussed.
