Vibration Control and Optimization in Composite Structural Elements by Use of Add-On Viscoelastic Materials

Abstract

The focus of the study was in three areas: (1) Development of new and efficient models for accurate prediction of structural damping ability; (2) Development and application of new strategies to the associated optimization problem, i.e., damping layer redistribution for maximizing damping subject to static stiffness, stress, weight and frequency constraints and (3) experimental quantification for comparison with analytical predictions.
