We have recently established, in close collaboration with experimentalists from geology, physics, geotechnical and agricultural engineering, a comprehensive first-of-a-kind knowledge base for state-of-the-art data, characterization and modelling of the behaviour of dense granular systems under quasi-static loading conditions. This behaviour is intrinsically multiscale and is arguably one of, if not, the most challenging to characterize and model of the gamut of granular behaviour encountered in practice. In particular, it exhibits self-organized pattern formation and co-evolution of emergent functional structures in the mesoscopic scale. Therefore, one of the great challenges in the field is to decipher a granular materials inherent structural design principles as it deforms in response to external loads. Herein we summarize key achievements from this research program, including those above and beyond what was originally proposed.
