A multi-scale approach to investigate desiccation cracking in clayey soils. The project plans to develop a model of the mechanism of drying shrinkage and associated cracking in soils. Soil desiccation cracking can adversely affect the stability and performance of many vital geo-infrastructures. For example, desiccation cracks have contributed to dam and slope failures incurring significant damages.

The project plans to develop a model of the mechanism of drying shrinkage and associated cracking in soils. Soil desiccation cracking can adversely affect the stability and performance of many vital geo-infrastructures. For example, desiccation cracks have contributed to dam and slope failures incurring significant damages. Our understanding of the mechanism of drying shrinkage cracking and ways to control or avoid such cracking in soils is not yet fully developed. This project aims to advance knowledge of the nature of crack initiation and propagation in clayey soils induced by moisture evaporation, through the use of advanced experimental and modelling techniques. Outcomes are expected to lead to new continuum models for reliable prediction of soil desiccation cracking.Read moreRead less
A complex systems approach to granular rheology: interconnecting topology, stability, dynamics and function. The response of granular materials (e.g. soil, rocks) to applied stresses and strains will be characterised in detail. Information mined from experimental and simulation tests will be used to develop robust predictive models of granular behaviour, crucial for effective earthquake mitigation as well as greener mining and construction technologies.

Summary
X-ray Microscopy Facility for Imaging Geo-materials (XMFIG). The X-ray Microscopy Facility for Imaging Geo-Materials (XMFIG) will allow the investigation, with near-synchrotron capabilities, of the three dimensional internal structures and chemical compositions of geo-materials under relevant environmental conditions by engineers, geologists and materials scientists.
