journal contribution
posted on 2011-05-16, 10:24 authored by Alessandro PalmeriAlessandro Palmeri, Sondipon AdhikariA novel state-space form for studying transverse vibrations of doublebeam
systems, made of two outer elastic beams continuously joined by an
inner viscoelastic layer, is presented and numerically validated. As apposite
to other methods available in the literature, the proposed technique enables
one to considerer i) inhomogeneous systems, ii) any boundary conditions and
iii) rate-dependent constitutive law for the inner layer. The formulation is
developed by means of Galerkin-type approximations for the fields of transverse
displacements in the system. Numerical examples demonstrate that
the proposed approach is accurate and versatile, and lends itself to be used
for both frequency- and time-domain analyses.
