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 insert ignore into journalissuearticles values(FSDT); shell theory is used for obtaining the equations. Then two methods have been applied for solution. These methods are differential quadrature insert ignore into journalissuearticles values(DQ); and discrete singular convolution insert ignore into journalissuearticles values(DSC);. The discrete forms of these equations have been given.
