The vibration and buckling behaviour of laminated plates subjected to a variety of uniaxial edge loadings have been studied based on finite element analysis (FEA) by incorporating shear deformation and rotary inertia. Towards this, the plate model is discretized by using a 9-noded isoparametric plate element with five degrees of freedom at each node. The effect of ply-orientations, boundary conditions, b/h ratios, loaded edge length and aspect ratios of the plate have been considered for the vibration and stability behaviour of the plate. The compressive buckling result shows that the plate is less susceptible to buckle when the position of in-plane load towards the edge of the plate and more susceptible to buckle towards the center of the plate.
