Résumé

A method which uses a simple experimental setup and a fast numerical code running on a personal computer is presented. Extraction of equivalent properties of small rectangular composite panels in terms of young's modulus, density and damping factor is possible. The measurement part of this hybrid method consist on a clamp fixture. The plate is excited by an electro-dynamic shaker and its mean quadratic velocity is measured.
