Free vibration analysis of orthotropic composite annular plate is investigated. First-order shear deformation theory (FSDT) is used for equation of motion. Two different kernels such as Regularized Shannon delta (RSD) kernel and Lagrange delta sequence (LDS) kernel are used. The method of discrete singular convolution (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.
