厚圆柱壳的非轴对称自由振动

Nonaxially Symmetric Free Vibration of Thick Cylindrical Shells

对厚圆柱壳的非轴对称自由振动进行了分析．其中除了包含通常的薄膜和弯曲效应外，还反映了转动惯性、横向剪切变形和横向挤压的影响．文中给出了固有频率的数值结果，并对由经典理论和改进理论所预示的结果进行了比较．

In this paper, the nonaxially symmetric free vibration of thick cylindrical shells is analysed. The present work contains, in addition to the usual membrane and bending effects, also the influences of rotatory inertia,transverse shear deformation and transverse normal extrusion. The numerical results on the eigenfrequency are given, and the results predicted by the classical and the improved theories are compared.
