Sound Scattering and Plasticity n Amorphous materials*

Plastic deformation in amorphous materials results from a succession of local irreversible rearrangements at the nanometric scale known as Transformation Zones. From a numerical point of view, these Transformation Zones are well described within the theory of Eshelby inclusions. In this talk, we will compare sound scattering in amorphous materials in the presence of inclusions. We first remind the signature of structural disorder on acoustic attenuation. We will then detail the role of heterogeneous elastic inclusions on sound attenuation and thermal transfers. Finally we will focus on the effect of Eshelby like inclusions on sound attenuation.
