We propose a model updating process to improve the quality of a finite element model (mass and stiffness parameters).

The method is applied to highly flexible structures.

A measurement technology used to acquire the experimental data in the absence of any information on the actual weightless and load-free structure is proposed.

The updating method is based on the concept of error in the constitutive relation.

The method is illustrated and validated on two examples.
