Abstract

A new finite element is developed that reduces the modeling required to define the constrained layer damping treatment. The new element emulates the traditional method of modeling constrained layer damping with plate elements on either side of a thin hex element. Trade studies are performed in the application of constrained layer damping treatments to beams and plates. The effects of the thicknesses of the constraining layer and the viscoelastic layer are studied as well as some studies on the location of the damping treatment.
