Abstract : Vibration of anti-symmetric angle-ply layered conical shell is studied including shear deformation using spline function approximation. The equilibrium equations are formulated in terms of displacement and rotational functions. These functions are approximated using Bickley-type splines to obtain the generalised eigenvalue problem. Parametric studies are made to analyse the effects of circumferential node number, length ratio and cone angle on the frequency parameter for number of layers and materials with ply orientations under different boundary conditions.
