Abstract:

Higher-order shell equations are developed for thick, orthotropic, circular cylinders undergroing axially symmetric, non-torsional, harmonic motion. Systems of governing equations for three, five, seven and nine mode theories are obtained from Reissners variational principle by assuming stress and displacement states which include higher-order terms through the shell thickness. Frequency spectrums and mode shapes obtained from the solution of the resulting generalized characteristic-value problems are presented and compared to known elasticity solutions. Author
