This paper examines the vibration behaviour of non-classically damped systems in the frequency domain. Errors in the frequency response incurred by neglecting off-diagonal entries of a diagonally dominant modal damping matrix are assessed. The exact response is shown to be equivalent to an infinite

An improved method to identify damping characteristics of a dynamic system is developed. The method identi"es damping characteristics of the system in matrix forms directly from its measured frequency response functions. Each di!erent damping mechanism is identi"ed in a distinct matrix.

An estimation strategy for extraction of isotropic material damping is presented. The method is based on a modal receptance model, material damping functions and experimentally measured frequency response functions (FRF). Least-squares estimation of modal parameters is done by projections of the mea
