Forced Harmonic Vibration of the Generally Orthotropic Cylindrical Shell with Inner and Outer Fluid Loading

Abstract

This report describes a modeled system comprised of an infinite shell with both inner and outer fluids subject to forced harmonic vibration in the longitudinal (x) and circumferential (0) directions. Two excitations are applied to the outer shell surface: normal pressure, Po, and longitudinal shear stress, Px. The equations of motion are derived, from first principles, for an elastic shell, including a full treatment of bending and rotatory inertia. The fluids are treated as linearly elastic, inviscid media and are subject to the wave equation in three dimensions. The stress-strain relationship for the shell is formulated to enable the treatment of isotropic, specially orthotropic, and generally orthotropic composite materials undergoing plane stress.
