Abstract
A modal model is developed for an elastic structure with linear viscous damping. The transfer functions and normalizations that are of use in experimental modal parameter estimation are given attention. Procedures for extraction of damped natural modes from experiment-derived residues are outlined. Mass-properties-related modal identities are obtained for the damped modes.
