This project expects to transform the understanding of granular materials and their behaviour by establishing explicit links between the macroscopic responses of the materials and their evolving microstructural properties. This should lead to revolutionary constitutive models for granular materials that possess true mechanisms of evolving grain-scale structures. The proliferation of these new models should allow development of reliable predictive computational tools for the modelling and assessment of field-scale failure involving granular materials, enhancing the capability to assess the integrity and stability of earth structures, and benefitting the Australian economy, environment and public safety.

该项目希望通过在材料的宏观反应和其不断演变的微观结构特性之间建立明确的联系来改变对颗粒材料及其行为的理解。这应该会导致颗粒材料的革命性本构模型，这些模型拥有演变颗粒尺度结构的真实机制。这些新模型的普及将使人们能够开发可靠的预测计算工具，用于模拟和评估涉及颗粒材料的现场范围的破坏，提高评估地球结构完整性和稳定性的能力，并使澳大利亚的经济、环境和公共安全受益。
