  • A very first combined application of finite element method (FEM) and differential quadrature (DQ) method to vibration and buckling problems of rectangular plates was presented. The mixed scheme combines the geometry flexibility of the FEM and high accuracy and efficiency of the DQ method. The accuracy of the proposed method was demonstrated by comparing the calculated results with those available in the literature. It is shown that highly accurate results can be obtained using a small number of finite elements and DQM sample points. The proposed method is suitable for the problems considered due to its simplicity and potential for further development.
