各种边界条件对称正交复合材料层板自由振动的解析法
AN ANALYTICAL METHOD OF FREE VIBRATION FOR LAMINATED PLATES INCLUDING VARIOUS BOUNDARY CONDITIONS
-
摘要: 寻求各种边界下的复合材料层板的解析解(除简支边界外)历来是不太容易的.本文以一阶剪切理论为基础,通过引入位移函数,得到了这类层板在各种边界条件下的解析解.将算例与Rayleish-Ritz等方法的结果作了比较.Abstract: The example shows thar the influence of various boundary conditions obviously exist,and the natural frequencies obtained by the analytical method proposed in this paper are lower than those of calculated results by using the approximate methods.
