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

We have attempted to express the frequency response functions of a linear and a quadratic non-linear system in terms of spectral vectors. These vector notations convey the system characteristics in physically realisable measures. One of the valuable tools to verify the non-linear system features is
