In this paper authors discuss the advancements made over years in the passive constrained layer damping (PCLD) technique used for structural vibration control. To start with, the paper presents a brief literature survey on passive damping techniques using viscoelastic materials (VEM) emphasizing unconstrained layer damping (UCLD) followed by PCLD. The discussion on PCLD technique includes different mathematical models and experimental investigations related to it. Finally, the various design modifications proposed by the different researchers in order to improve the performance of conventional PCLD configuration in presented.
