Abstract: In dynamics, the effect of varying the constitutive materials’ thickness of a two‐layered beam is investigated. Resonance frequencies and damping variations are determined. It is shown that for specific thicknesses the coupling of longitudinal and flexural vibrations influences the global modal damping ratio significantly.
