Data on role of shape on fast granular flows of irregular grains

•Design experimental protocols to characterize the behaviour of a model system composed of non-spherical 3D printed grains, performing optical experiments using high-speed imaging. (UTWENTE, WRCP)•Design experimental protocols to execute X-ray micro-tomographic characterization of the microstructure of granular materials and its evolution under mechanical loading. (UGA, UTWENTE)
