In this paper, harmonic behaviour of laminated composite skew plates is presented with a symmetric and anti-symmetric arrangement of layers. The convergence and validity of the model have been checked by comparing different type of example available in published literature. From the comparison study, it can be easily observed that proposed model is being capable of solving the skew structures with adequate accuracy. The effects of various skew angles, lamination scheme and number of layers have

It is clear from the results that the maximum resonance amplitude occurs at the first fundamental mode of vibration at different skew angle. Finite element package ANSYS is employed for analysis of the plates. The SHELL281 element is chosen to mesh the model.
