Sandwich structures are a key member for many structures. They are finding increasing application in aerospace, marine and construction industries. In some of these applications, these materials are subjected to dynamic loads. Predictive maintenance is important consideration to predict and prevent future problems. A comprehensive maintenance and operations programs can identify and eliminate many potential problems, helping to avoid catastrophic failures. Delamination damage leads to stiffness loss of the structure, the modal properties like natural frequencies, damping ratio and mode shapes may vary. The present article does the experimental study on the free vibration analysis of multilayered laminated sandwich beam.
