Abstract
Abstract THE MAGNITUDE AND FREQUENCY RANGE OF DAMPING PROVIDED BY A CONSTRAINED LAYER DAMPING STRUCTURE ARE IMPROVED BY THE ADDITION OF AN EXTENSIONAL DAMPING LAYER. IF THE SHEAR DAMPING LAYER OF THE CONSTRAINED LAYER STRUCTURE AND EXTENSIONAL DAMPING LAYER PROVIDE PEAK DAMPING AT DIFFERENT TEMPERATURES, EFECTIVE DAMPING WILL ALSO BE PROVIDED OVER A WIDER TEMPERATURE RANGE THAN WITH THE SHEAR OR EXTENSIONAL DAMPING LAYERS ALONE.
