摘要

A comprehensive vibration study of thin, laminated, cylindrically curved shell panels (based on the shell theory of Love with a modification by Arnold and Warburton) is conducted by using the h-p version of the finite- element method (FEM). Polynomially enriched stiffness and mass matrices are derived from classical shell theory using Symbolic Computing, and then stored in algebraic form for a single, generic element. A number of such elements may then be combined to form the global stiffness and mass matrices for a more general co-axial and/or co-circumferential assembly. Any of the classical edge conditions, or point corner supports, may be accommodated in the analysis; forcing may be applied through one or more point forces acting normal to the shell surface.
