Numerical Methods for FGM Composites Shells and Plates

Abstract

Main formulations for free vibration analysis of functionally graded composite shells have been given in numerical concept. Equations of motions for conical shells are listed in differential form.  First-order shear deformation (FSDT) shell theory is used for obtaining the equations. Then two methods have been applied for solution. These methods are differential quadrature (DQ) and discrete singular convolution (DSC). The discrete forms of these equations have been given.
