The determination of frequencies of laminated conical shells via the discrete singular convolution method

The discrete singular convolution (DSC) algorithm for determining the frequencies of the free vibration of laminated conical shells is developed by using a numerical solution of the governing differential equations of motion based on Love's first approximation thin shell theory.By applying the discrete singular convolution method, the free vibration equations of motion of the composite laminated conical shell are transformed to a set of algebraic equations.Convergence and comparison studies are carried out to check the validity and accuracy of the DSC method.
