Abstract: Lightly damped systems exhibit strong resonances which should be accurately characterized to prevent potential harmful damage in real-world applications. Characterizing these resonances using frequency response function (FRF) measurements is challenging due to long transient behavior… read more here.

Abstract: Quantifying the level of nonlinear distortions and time-varying effects in frequency response function measurements is a first step toward the selection of an appropriate parametric model structure. In this paper, we tackle this problem in… read more here.
