In this study, experimental investigation vibration behavior of square composite plate by electronic speckle pattern interferometry (ESPI) is employed. Resonant frequencies and corresponding mode shape are obtained experimentally using the present method. The numerical calculations by the finite element method (Cosmos) are performed and the results are compared with the experimental measurements. Good agreement is obtained for both results of resonant frequencies and mode shapes. Theory of plate vibrations allows us to determine Poisson's ratio v, Young's modulus E and shear modulus G from the measured resonant frequencies.
