Résumé

During the manufacture processes of their critical parts, industrials use non destructive techniques to ensure the quality of their products. Among those, ultrasonic testing is a widespread method. However, structure borne noise remains a complex problem for results interpretation during ultrasonic testing. Therefore, it is a matter of interest to improve our understanding of the propagation of ultrasonic waves in polycrystalline materials. The use of mean field and statistical models and are well known and the recent increasing of computing capabilities (due to hardware enhancement and HPC methods) allows today more realistic computations. In this context, we propose to develop a high fidelity tool that can simulate the propagation of ultrasonic waves polycrystalline materials taking into account the complexity of their characteristics. To do so, we apply different finite element methods on realistic microstructures generated with Laguerre-Voronoı̈ tesselations and 2D/3D reconstructions from EBSD data. The solved PDEs are based on the Momentum Balance Equation and the Stress-Strain relation.
