Groupement De Recherche Européen : GDRE-US

It is a workshop of the European GDR. In the lines of previous one or two day scientific meetings, this coming workshop will focus on a specific topic of the network. In the present case, it is Nonlinearities in acoustics, specially contact nonlinearities, after those of Paris, Manchester, Bristol, on the same topic.

Scientific committee : Alain Léger, Bruno Lombard, L.M.A. Marseille Organizing committee : Angélique Guitard, Stéphane Junca, Bernard Rousselet, Labo. J.A.D. Nice.
