✦ Synopsis
In this paper, a method of analysis for the free vibration of a three-layer sandwich arch with an elastic or viscoelastic core, and with various kinds of axis-shape and boundary conditions is presented. The characteristic equation of the free vibration is derived by applying Green functions. The Green functions are obtained in a discrete form for various kinds of sandwich arches with non-uniform cross-section and radius of curvature. They enable the setting up of the frequency equation in eigenvalue form.
