January 9-10, 2014
par - 27 octobre 2013
Workshop organized by Mourad Bentahar LAUM Le Mans, Bruno Lombard, Joseph Moysan, Cédric Payan Aix-Marseille University and LMA.
The CNRS research network GDRE-US will organize the next workshop dedicated to nonlinear acoustics at the IUT d’Aix-Marseille in Aix en Provence (France) on January 9-10, 2014. This workshop will be a good opportunity for participants, whose research topics are in the field of nonlinear acoustics, to focus on the recent advances in material and contact nonlinearities.
The first announced speakers are : Koen Van Den Abeele, Vitali Gusev, Igor Solodov, Claudio Pecorari, Marco Scalerandi, Stéphane Junca, Anissa Meziane, Guillaume Renaud, Vincent Tournat, Cédric Payan, Mourad Bentahar.
We also warmly welcome contributions from PhD students and invite them to participate to the workshop.
The « ANR project ISABEAU » (Innovating for Structural Adhesive Bonding Evaluation and Analysis with Ultrasounds ) supports this conference.
