Vibration of a materially monoclinic, thick-wall circular cylindrical shell

The resonant vibration frequencies of a fiber-reinforced, thick-wall, circular-cylindrical shell of finite length which is materially monoclinic are analyzed. The degree of material anisotropy precludes a closed-form solution and so an iterative, yet exact, method is used. The analytical method is validated by comparison of results with previously published results for a homogeneous, isotropic thin shell, and an orthogonally stiffened-thin shell modeled as orthotropic. Results for a materially monoclinic, thick-wall shell with free-free end conditions are compared with experimental results obtained by the present investigators.
