Damping Matrices Revisited
Publication: Journal of Engineering Mechanics
Volume 140, Issue 8
Abstract
After a brief review of the problems entailed by the so-called proportional damping matrices, this paper elaborates on a simple technique to construct damping matrices that guarantee the fraction of damping in each mode to be positive and adequate and accomplishes this without solving for either the modes or the natural frequencies. Although the resulting matrices do not generally satisfy the proportionality condition, this fact is irrelevant for the purposes to which such matrices are put.
