Abstract
This paper is concerned with the optimal damping of beams or plates partially covered by viscoelastic constrained layers. The objective function is to maximize the modal damping factor of one (or several) mode(s). During the optimization process, the selected mode shapes are those of the undamped associated structure. A convenient finite element model for the beam or the plate dynamic analysis is used. The possible dimensions and locations of the viscoelastic layers are determined by the use of a genetic algorithm.
