A Review on Experimental Investigation on Damping of Layered and Riveted Structure Beam

In the present work, the mechanism of damping in layered and jointed structures with connecting rivet have been extensively studied. A lot of experiments have been conducted on a number of specimens with connecting rivet of various diameters, length and thickness to study its effect on the damping capacity of the layered and jointed structures and to establish the authenticity of the theory developed. Intensity of interface pressure, diameter of the connected rivet, length and thickness of beam, number of layers, kinematic coefficient of friction at the interfaces and frequency and amplitude of excitation are found to play a major role on the damping capacity of such structures. This design concept of using layered structures with riveted joints can be effectively utilized in trusses and frames, aircraft and aerospace structures, bridges, machine members, robots and many other applications where higher damping is required.
