Damage detection of sandwich material used in the ship structure has attracted more awareness to providing diagnostics for Structural Health Monitoring (SHM) systems. This study reported damage identification of sandwich material based on the Random Decrement Method (RDM) using experimental and numerical approaches. The investigation was assumed by modeling the material in two conditions which are undamaged and damaged conditions to analyze the dynamic behaviors of vibration response. The results of the vibration response obtained a similar trend between undamaged and damaged material conditions. Furthermore, a decreased stiffness occurs due to damage to the sandwich plate. Therefore, the random decrement method can be selected as a detection method for identifying damage with fair accuracy and obtaining sustainability for the ship structure.
