Abstract
A finite element model is developed to investigate the vibration and energy dissipation characteristics of elastic-viscoelastic-elastic composite (EVEC) beams. The theoretical energy dissipation characteristics of the EVEC beams are quantized by the loss factors. Two energy dissipation mechanisms, namely the shear and compression damping are combined in the finite element model. Numerical examples are provided to verify the finite element model. The instructive conclusions are important to make the EVEC beam more suitable for controlling structural vibrations and noise.
