1 May 1994 Models for structural damping for laminated beams due to interfacial slip
Author Affiliations +
Three models for two-layered beams in which slip can occur at the interface are described. In the first, beam layers are modelled under the assumptions of Timoshenko beam theory. Along the interface a `glue layer' of negligible thickness bonds the surfaces so that a small amount of slip is possible. Dissipation is assumed to be proportional to the rate of slip. The second is obtained from the first by letting the shear stiffness of each beam tend to infinity. The third is obtained from the second by assuming that the moment of inertia parameter is negligible. In this case an analog of the Euler-Bernoulli beam is obtained which exhibits frequency- proportional damping characteristics.
