Abstract

The new version of differential quadrature (DQ) method is extended to analyze the free VIBRATION of thin sector orthotropic plates on the Pasternak elastic foundation with various sector angles and elastic parameters. Detailed formulations are given. Comparisons are made with existing analytical and/or numerical data. Numerical results indicate that convergence can be achieved with increasing in number of grid points. The accurate results could be obtained with 9x9 or even higher grid. It is found that the results are influenced by grid spacing and for obtaining the accurate and reliable result non-uniform grid should be used.
