Abstract #

To characterise any material with sound waves, the wave will propagate through several layers before reaching the material. If that material is a random particulate material, then to date there is no simple model to deal with the layers. In this talk we show how extending the quasi-crystalline approximation (a technique from statistical physics) to layers leads to clear and simple models which separate the influence of the microstructure from the material geometry.
