In this paper a method is presented to identify local non-linear stiffness and damping parameters from dynamic response data. The non-linearity is being taken into account by assembling non-linear two-degree-of-freedom elements into larger linear finite element models. Special care has been taken to

This work outlines the basic formulation for the frequency response function based updating method and discusses several possible solution strategies. Using simulated experimental data, systematic studies are conducted in the case of a simple beam structure to investigate the uniqueness of the updat
