Building the bridge from a microscopic towards a macroscopic description of the flow of amorphous media

Objectif

Although disordered media are ubiquitous in everyday life in form of emulsions, pastes, granular materials, foams and metallic glasses, there is still little known about a possible macroscopic description of such type of materials. Despite the seemingly very different nature of the so called soft and hard versions of amorphous media, both lead to similar challenges when it comes to theoretical concepts and modeling issues. Here, we propose a bridging technique, starting from a first principle microscopic representation on the bases of molecular dynamics, towards a macroscopic mean field description of the plasticity of amorphous materials. We are considering disordered media, subject to a shear force, that will eventually cause the material to yield under sufficient loading. It is a commonly accepted point of view that the flow of glasses is a net result of individual structural rearrangements on the atomic or molecular level. Hence, it should be possible to derive a mesoscopic stochastic model, that allows for the application of statistical methods to conclude with the much sought after mean-field equations of amorphous plasticity. The establishment of such a description is not only of interest from a unifying theoretical point of view, but will also offer a key tool in practical engineering questions.
