摘要
Abstract
Love' s first approximation theory was used to analyze the natural frequency of rotating functionally graded cylindrical shell. In order to verify the validity of the present method, natural frequencies of the simply supported non-rotating isotropic cylindrical shell and functionally graded cylindrical shell were compared with the available published results and good agreement was obtained. The effect of power law index, the wave number along the x and 6 direction , thickness to radius ratio on natural frequencies of the simply supported rotating functionally graded cylindrical shell was investigated by several numerical examples. It is found that the fundamental frequencies of the backward waves increased with the increasing rotating speed while those of forward waves decreased with the increasing rotating speed, the forward and backward waves frequencies increased with the increasing thickness to radius ratio.关键词
