| 摘 要： | 本文用三维弹性力学理论研究绕径旋转横观各向同性圆球壳的变形和应力分布，给出任意厚度圆球壳的位移和应务的封闭形式解以及数值结果。研究表明球壳上的位移和应力大小与旋转角速度的平方成正比，球面内的正应力远大于径向正应力和剪应力。

| Abstract: | In this paper, the deformation an.d the stress distribution of a transversely isotropic spherical shell rotating about a diameteral axis is investigated on the basis of three-dimensional elasticity. A closed-form solution and numerical results regarding the displacements and stresses in a spherical shell of arbitray thickness are presented. It is shown that the absolute values of displacements and stresses in the spherical shell are directly proportional to the square of the rotating angular velocity, and the normal stresses on the spherical surface are larger than the normal stress in the radial direction and the shearing stress. |
