The present work deals with the parametric instability of multi-layered symmetric sandwich beams with alternate elastic and viscoelastic layers, subjected to periodic axial load. The equations of motion and boundary conditions are derived by applying Hamilton's principle, and the general Galerkin me

The parametric instability of a partially covered, symmetric, simply supported sandwich beam with viscoelastic covers and subjected to an axial pulsating load is studied. The effects of single as well as separate partial viscoelastic covers, cover ratio and location of covers on the static buckling

The parametric instability of a beam under electromagnetic excitation was investigated experimentally and analytically. In experiment an electromagnetic device, acting like a spring with alternating sti!ness, was designed to parametrically excite the beam. The frequency and the amplitude of the exci
