The operational modal analysis methods based on output-only measurements are well-
known and applied in linear systems. However, they are not so well developed for nonlinear …

In this study, the discrete-time Volterra series are used to update parameters in a nonlinear
finite element model. The main idea of the Volterra series is to describe the discrete-time …

The linearity assumption in the structural dynamics analysis is a severe practical limitation.
Further, in the investigation of mechanisms presented in fighter aircrafts, as for instance …

Nonlinear behavior can be important for the monitoring of the structural state of mechanical
systems since it can be mistakenly classified as a damage in the systems. However …

The goal of this paper is to verify the influence of uncertainties in the identification of Volterra
kernels applied in a single degree-of-freedom nonlinear model with cubic stiffness …

The aim of this paper is to identify a nonlinear model using time responses obtained from a
sine sweep excitation applied to a simplif ied solar array structure. The nonlinearity is mainly …
