This article focuses on the application of the differential quadrature method (DQM) for the buckling analysis of one-dimensional (1D) composite laminated beam-plates. The DQM formulation of the problem is presented. The formulation accounts for the effects of shear deformation and bending-extension coupling. The governing 1D differential equations were transferred into a system of linear algebraic eigenvalue equations. A standard eigen-solver was used to obtain the delamination buckling loads and the associated mode shapes. Several case studies were used to investigate some of the parameters that affect the buckling response of such composite beams. The study demonstrates the excellent accuracy and efficiency that can be obtained by applying the DQM to treat delamination buckling of composites.
