Analytical Study of Dynamic and Vibrational of Composite Shell with Piezoelectric Layer using GDQM Method

Piezoelectric materials, due to their electromechanical coupling properties, are widely used as actuators and sensors in intelligent structures control vibrations bends of multilayer sheets with piezoelectric layers. In this paper, the response free a composite shell new Generalized Differential Quadrature Method (GDQM) for different boundary conditions is investigated. The governing equations obtained by assuming first-order shear theory using Hamilton's principle. generalized quadrature differential method solve equations. To use method, coding has been done MATLAB software. Due same thickness layers, number layers increases total constant, each layer decreases, consequently decreases. Comparing results work other researchers shows that good accuracy.
