Seeing the discrete in a continuum: an integrated numerical-rheological-experimental approach towards high resolution micromechanical continuum models of granular media

由于对颗粒流变学的了解不足，涉及颗粒材料的工艺很复杂，很少达到设计能力的60%以上。拟议项目的短期好处包括：提高对颗粒介质流变性的洞察力；具有无与伦比的预测能力的经过实验验证的微观机械本构模型；与复杂材料科学密切相关的多尺度过程分析的建模技术。长期效益是颗粒物系统的计算机辅助设计、生产和管理所需的可靠性模型。这些模拟工具将增强澳大利亚在价值数十亿美元的颗粒和岩土行业的竞争优势。

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 dollar particulate and geotechnical industries.
