Seeing the discrete in a continuum: an integrated numerical-rheological-experimental approach towards high resolution micromechanical continuum ...
Grant number: DP0558808
Processes involving granular materials are complex and rarely reach more than 60% of the design capacity, due to inadequate understanding of granular rheology. The short term benefits of the proposed project are: improved insights on the rheology of granular media; experimentally validated micromechanical constitutive models with unmatched predictive capabilities; modelling techniques in the analysis of multiscale processes, germane to the Science of Complex Materials. The long term benefits are models of the required reliability for computer-aided design, production and management of particulate systems. These simulation tools will enhance Australia's competitive edge in the multi-billion d..View full description
