Effectiveness of Extensional Damping Using Rubber as Layer
Abstract: Structural damping treatments are free layer damping and constrained layer damping, made of metal and viscoelastic layer combinations which help to reduce vibrations. A free layer damping (FLD) treatment also known as Extensional Damping is formed by applying a coating of a damping material to one side of a structure. The treatment may be symmetric or asymmetric, and applied to beams, plates or shells in bending or in tension. In …
