Nonlinear system identification is a vast research field, today attracting a great deal of
attention in the structural dynamics community. Ten years ago, an MSSP paper reviewing …

This paper develops the Kron's substructuring method for updating large-scale nonlinear
structures. The global structure is divided into linear and nonlinear substructures. By using a …

Mechanical joints usually affect structural dynamic responses, leading to local nonlinear
stiffness and damping. In this paper, hysteresis Iwan model is discussed in detail to describe …

The damage detection problem in mechanical systems, using vibration measurements, is
commonly called Structural Health Monitoring (SHM). Many tools are able to detect …

This paper is a survey of the literature about the nonlinear updating process. It is focused on
the computation of the difference between the numerical model and the reference data as …

Nonlinearities in the dynamical behavior of mechanical systems can degrade the
performance of damage detection features based on a linearity assumption. In this article, a …

In this paper, structural dynamic model updating has been utilized in experimentally
evaluating the extent of damage at six locations of a damaged cantilever beam structure. Six …

The damage detection problem becomes a more difficult task when the intrinsically
nonlinear behavior of the structures and the natural data variation are considered in the …

Mathematical modeling of mechanical structures is an important research area in structural
dynamics. The goal is to obtain a model that accurately predicts the dynamics of the system …

Aim of this research paper is to present the application of Derringer's function based
weighted model updating method for damage detection in a cantilever beam structure …
