Constrained layer damping is a mechanical engineering technique for suppression of vibration. Typically a viscoelastic or other damping material is sandwiched between two sheets of stiff materials that lack sufficient damping by themselves. A theoretical analysis of the constrained layer damping treatment for thin metallic panels is conducted. Analysis developed by Ross, Ungar and Kerwin is used to predict the response of damped three layer system, assuming that the properties of the damping material are known. Numerical simulation of the constrained damping treatment is done using ANSYS software. The results obtained from the numerical simulation are compared to that from theory to understand the range of applicability of the analytical solution.
