A composite beam consists of laminate consisting of more than one lamina bonded together through their thickness. Composite materials have interesting properties such as high strength to weight ratio, ease of fabrication, good electrical and thermal properties compared to metals. The equation of motion for the viscoelastic sandwich beam is studied. Different specimens have been modelled by varying the core layers and face layers and studied under the fixed-fixed and cantilever boundary conditions for modal analysis. A finite element model has been developed for the three layer viscoelastic sandwich beam. The sandwich beam is modelled using linear displacement field at face layer and non-linear displacement field at core layer. The Natural frequencies are obtained for various models using different core materials and boundary conditions. The results obtained are compared with the earlier existing and experimental results.
