Abstract: The buckling analysis of single layered orthotropic and cross ply laminated composite plate using trigonometric higher order shear deformation theory and meshless method based on the finite point formulation using multiquadric radial basis function is presented. The convergence of the present method is studied for laminated plates with different shape parameters. After the proper convergence of present method several numerical examples of plates subjected to uniaxial and biaxial loading are under taken. The effect of an anisotropy ratio of material on critical buckling load of the plates is also reported with proper validation of present results with earlier published literature.
Keywords: Composite plate, trigonometric theory, buckling, meshless method.
