Physics-informed hydrodynamic model for clay across scales

该项目旨在通过将微观和介观机制的直接观察与严格的物理原理相结合，开发粘土宏观行为的预测模型。该项目预计将使用新的X射线和光学方法跟踪粘土骨料在可变载荷和湿度下的膨胀或收缩。一个关键的预期结果是一个强大的流体动力学模型的粘土，合理化观察到的现象的发展。预期成果包括粘土动力学的准确预测，无论是快速滑坡或缓慢干燥和湿润。由于澳大利亚大部分地区都经历了干旱和洪水，该项目将有利于粘土上关键基础设施的寿命和安全。

This project aims to develop a predictive model for the macroscopic behaviour of clay by combining direct observations of microscopic and mesoscopic mechanisms with rigorous physical principles. The project expects to track clay aggregates as they expand or shrink under variable loads and moistures using novel X-ray and optical methods. A key anticipated result is the development of a robust hydrodynamic model for clay that rationalises the observed phenomena. Expected outcomes include the accurate predictions of clay dynamics, either fast during landslides or slow under drying and wetting. As much of Australia experiences droughts and floods, this project should benefit the longevity and safety of critical infrastructure situated on clay.
