Offre : Post-doctorat Ifsttar – Ultrasonic Surface Waves

Titre du poste : Post-doctorat (H/F) : Ultrasonic Surface Waves
Description du poste : Sujet :
We are looking for a highly motivated post-doc to take up a position on ultrasonic surface waves for the Non Destructive Evaluation (NDE) of a very heterogeneous material, concrete. You will work on a project funded by the French National Research Agency (ANR) within the framework of a consortium dealing with the safety of concrete nuclear containment wall (PIA-ANR-ENDE and PIA-ANR-MACENA).

– Your first goal will be to optimise and validate in the laboratory an original experimental device under development at Ifsttar that uses multiple sources and multiple receivers to recover ultrasonic surface waves coherent field.

– Your second objective will be to link this experimental device to recent in-house developments on surface waves dispersion curves forward modelling and inversion to recover intrinsic properties of very heterogeneous material. This task requires a survey of our codes in order to reshape and integrate them in a robust and reliable framework based on one hand on the physics of surface waves propagation and on the second hand on the precision requested. The programming environment for the integration work will be Python.

– The third task will be to carry out experiments on an outstanding test facility owned by Electricité de France (EDF), the Vercors mock-up, to process the signals and to confront your results with data coming from embedded sensors as well as information provided by other non destructive measurements collected by partners.

At the end of your post-doc a surface waves NDE experimental device associated with a robust measurement and interpretation methodology, validated on a full scale specimen, will be made available to practitioners involved in the non destructive evaluation of concrete in general and nuclear containment wall in particular. This post-doc will be the occasion to built and show a broad scale of expertise and to work with researchers involved in the whole chain of ultrasonic innovation.

ou will be expected to publish scholarly papers and attend an international conference.

Type de contrat : Post-doctorat 12 mois à temps plein
