摘要
利用从弹性力学的三维基本方程导得的状态方程 ,结合层合近似模型 ,求得了柱型正交各向异性功能梯度圆柱壳的自由振动频率 ,给出了数值算例 ,并与前人结果作了比较 。
A laminate approximated model and a state equation derived from the three-dimensional equations of elasticity are employed to solve the free vibration of a cylindrically orthotropic functionally graded cylindrical shell. Some numerical examples are presented and compared with those results provided by others. The influence of some related parameters on frequencies is finally discussed.
