Abstract: The grid spacing plays an important role in the buckling analysis of composite laminated plates by the Differential Quadrature (DQ) method. Two formulae are proposed to compute the grid spacing and the convergence of the DQ method is then investigated.It is found that the DQ methOd with the proposed grid spacings gives satisfactory resuIts for vari-ous benchmark problems considered in this paper.
