Estimation of the area of a reverberant plate using average reverberation properties

Hossep Achdjian, Emmanuel Moulin, Farouk Benmeddour, Jamal Assaad

This paper aims to present an original method for the estimation of the area of thin plates of arbitrary geometrical shapes. This method relies on the acquisition and ensemble processing of reverberated elastic signals on few sensors. The acoustical Green's function in a reverberant solid…

The Faraday instability in miscible fluid systems

S.V. Diwakar, Farzam Zoueshtiagh, Sakir Amiroudine, Ranga Narayanan

The Faraday instability arising in distinct miscible fluid layers, when the parametric forcing is parallel to the gravity vector, is analysed. A time-dependent density gradient is established from the moment the fluid layers are placed in contact with one another. The operating parameters in a…

Modelling based on Spatial Impulse Response Model for Optimization of Inter Digital Transducers (SAW Sensors) for Non Destructive Testing

Dame Fall, Marc Duquennoy, Mohammadi Ouaftouh, Bogdan Piwakowski, Frédéric Jenot

This study deals with modelling SAW-IDT transducers for their optimization. These sensors are specifically developed to characterize properties of thin layers, coatings and functional surfaces. Among the methods of characterization, the ultrasonic methods using Rayleigh surface waves are…

An overview of 15 years of French collaborative projects for the characterization of concrete properties by combining NDT methods

Jean-Paul Balayssac, Vincent Garnier, Géraldine Villain, Zoubir Medhi Sbartaï, Xavier Derobert, Bogdan Piwakowski, Denys Breysse, Jean Salin

This communication aims to present the evolution of the activities carried out in France for assessing concrete properties by combining NDT methods. An important effort was done for improving NDT methods, particularly for more suitable on-site applications (for instance use of ultrasonic non-…

Tonpilz Underwater Acoustic Transducer Integrating Lead-free Piezoelectric Material

Rémi Rouffaud, Christian Granger, Anne-Christine Hladky, Mai Pham Thi, Franck Levassort

A Tonpilz transducer based on lead-free piezoelectric material was fabricated, modeled and characterized. The stack is composed of two rings of doped BaTiO 3. This composition was initially chosen due to good electromechanical performance (k t at 40%) and high mechanical quality factor (Q m over…
