FREE VIBRATION OF BIMODULUS LAMINATED CROSS-PLY CONICAL PANELS

摘要

The problem is formulated employing first order shear deformation theory. The governing equations, obtained using Lagrange's equation of motion, are solved by finite element method. A detailed parametric study is carried out to study the influences of thickness ratio, aspect ratio, semi-cone angle, and number of layers on the free vibration natural frequencies and neutral surface location of bimodulus cross-ply composite laminated conical panels.
