Free flexural vibration behavior of laminated angle-ply elliptical cylindrical shells

This paper deals with the free flexural vibration characteristics of anisotropic laminated angle-ply elliptical cylindrical shells using finite element approach. The formulation is based on first-order shear deformation theory. The present model accounts for in-plane and rotary inertia effects. A detailed study is carried out to highlight the effects of shell geometry, cross-sectional properties, lap-up and ply-angle on the natural frequencies pertaining to different types of modes of vibrations of non-circular shell structures.
