Abstract

Laminated metals consisting of different metallic materials are expected to have advantages over single metal materials; high damping capability is one such additional value. This report describes a numerical approach for evaluating the damping capability of laminated metals. For this purpose, we employed the classical lamination theory, which is widely applied to FRPs or damping steels with viscoelastic layers, in this study. The modal characteristics (natural frequencies and natural mode shapes), specific damping capacity and modal loss factor, and frequency response functions (FRFs) against excitation input for laminated metal beams are calculated using the proposed method. Those results are compared with those using a finite element (FE) analysis and experiments, and the validity of the proposed method has been confirmed. Numerical studies are conducted to search for highly advantageous configurations of two metals (aluminum and copper) in terms of lightweight, high stiffness, and high damping performance.
