This work represents vibration analysis of a viscoelastic sandwich beam. Three layered viscoelastic sandwich beam combination of metal as well as non-metal is modeled using CATIA software. Different specimens have been modeled by varying the core layers (Natural Rubber and Neoprene Rubber) and face layers. The Natural frequencies are obtained for various models using different face layers and boundary conditions. Experimentation was also conducted in order to verify the results obtained from finite element analysis. The results clearly show that there is decrease in natural frequency of beams modeled with Neoprene as a core layer compared to the rubber for the fixed-free boundary conditions.
