Numerical modeling of surface elastic wave scattering in polycrystalline materials
Original language description
Grain-boundary scattering of acoustic waves in polycrystalline materials is studied with analytical and numerical methods in the presented paper. In particular, the attenuation of Surface Acoustic Waves (SAWs) propagating through a polycrystalline microstructure is investigated. A three dimensional timedomain finite-element method (FEM) is utilized for the numerical simulation, whereby the granular microstructure is modeled by Voronoi tessellation. The resulting frequency-dependent attenuation coefficients are compared to an explicit analytical model.
