Buckling analysis of composite plates using differential quadrature method (DQM)

The differential quadrature method (DQM) is a numerical technique of rather recent origin,rnwhich by its continually increasing applications in different problems of engineering, is a competingrnalternative to the conventional numerical techniques for the solution of initial and boundary valuernproblems. The work of this paper concerns the application of the DQM in the area of the buckling of multirnlayered orthotropic composite plates with various boundary conditions the buckling of multi layeredrncomposite plates with constant and variable thickness under axial compressive static loading is considered.rnThe effects of fiber orientation and boundary conditions on static behavior of composite plates arernpresented .The comparison of results from the present method and those obtained from NISA II softwarernshows the accuracy and reliability of this method.
