Physics-informed hydrodynamic model for clay across scales

点击翻译按钮获取中文摘要

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.
