Abstract :Free vibration analysis of orthotropic composite annular plate is investigated. First-order shear deformation theory insert ignore into journalissuearticles values(FSDT); is used for equation of motion. Two different kernels such as Regularized Shannon delta insert ignore into journalissuearticles values(RSD); kernel and Lagrange delta sequence insert ignore into journalissuearticles values(LDS); kernel are used. The method of discrete singular convolution insert ignore into journalissuearticles values(DSC); is used for numerical simulation of governing equations to obtain the frequency values. It is shown that the convergence and accuracy of the DSC method is very good for vibration problem of orthotropic annular plate.
Keywords : Frequency, annular plate, discrete singular convolution, composite laminated
