✦ Synopsis

A finite element formulation combined with a new material model has been developed for the traditional multilayer beam incorporating viscoelastic material having non-linear behavior. The viscoelastic material was confined between the stiff layers and worked as a damping layer. A non-linear dynamic analysis in the time domain was carried out for the multilayer beam subjected to dynamic loadings. In the analysis the boundary conditions for the beam are either simple or clamped and the exerted loadings include transient impulse loading, harmonic excitation and a random type process. The non-linear responses in the time domain for the multilayer sandwich beam containing the viscoelastic material were compared to one without the viscoelastic material. The time domain dynamic behavior for the multilayer beam with variant boundary conditions, dimensions and loading types is also discussed.
