For polycrystalline materials, such as metals and sand, mechanical properties are largely defined by the granular texture, the grain stress/strain states and the evolution of these. In this experiment we will test time-of-flight 3D Neutron Diffraction, a new experimental method that allows in situ analysis of microstructures and micro-structural processes in multi-grain/polycrystalline materials. The method derives from 3D X-Ray Diffraction, an extension of standard single crystal diffraction techniques to multigrain crystallography. We will use 3D Neutron Diffraction to measure individual crystallographic orientations and strains of the grains in an artificial quartz sand sample. Analysis of this material will help the method development, and is of key interest in studying the mechanics of force-transfer and failure in granular materials.
