Abstract: Skew laminated composite plates with cut-outs are used in many engineering applications like fins, wings and tails of aero planes, hulls of ships and parallelogram slabs in buildings, complex alignment problems in bridge design etc. The structure used in these applications, are often subjected to dynamic force which creates vibration. Based on the First-order Shear Deformation Theory (FSDT), this study deals with harmonic analysis of moderately thick laminated composite skew plates with cut-outs using the finite element package ANSYS. The effect of various geometries of the cut-out, on the resonance point has been investigated. An 8 node 281 shell element is adopted to mesh the plate geometry. The accuracy of the present analysis is shown in some typical cases. The results are compared with existing results based on other numerical methods and observed to be in close proximity.
