| Abstract: | In this paper,the spline function method(SFM)is improved by using the method of integration of fundamental spline function with multipoints.Free vibrations of rectangular and annular thick plates with uniform or varying thickness are analysed by the improved SFM.This paper shows that the improved SFM has the following advantages:high accuracy,less computing work,good adaptability,and convenience in application. |
