摘要
选取一个全部满足自由边边界条件和自由角点条件的挠度函数，它由三角函数和多项式组成。利用方法得到弹性地基上自由边矩形板弯曲、稳定和振动问题的解．并给出了数值算例．
in this Paper,the flexual function which consists of trigonometrical function and Polynomial expression is selected.It satisfies all the boundary conditions on free edges and the conditions at four free corner Points.Solutions for bending,stability and vibrations of the rectangular plates with four free edges on elastic foundations by method of Galerkin are obtained.In this Paper,the results of numerical example are given.
