Abstract
Damping can be one of the more perplexing aspects of structural dynamics because it is much less intuitive and “clean-cut” than concepts like stiffness and mass. Nevertheless, analysts should not view damping simply as an unfortunate side issue in structural dynamics, but as an opportunity for creative design work aimed at suppression of unwanted vibrations. This paper presents a review of some basic concepts in damping and how damping is treated in finite element analysis. It also presents some new techniques that have been developed to support optimization of damping for structures.
