Full PhD Scholarship in Developing a constitutive model for transition granular materials at the University of South Australia.
If you are seeking to advance your career in civil engineering and interested in granular materials, the University of South Australia – Australia’s University of Enterprise – is offering a hands-on project-based PhD in partnership with CMW Geosciences.
Granular porous materials are collections of discrete particles, and their hydromechanical behaviour is affected by particle size. Currently, they are classified as either sand (>0.075mm) or silt/clay (<0.075mm), depending on whether their behaviour is dominated by gravity or electrostatic forces, respectively.
While the mechanics of these two types of granular materials are well known, most natural soils, tailings and granular ores (iron ore, coal, bauxite, phosphate) are collections of both sand-silt/clay, i.e. transition granular materials. The mechanics of the latter are not so well understood, so the response of these materials is often analysed based on the dominant particles, which often causes optimistic design and results in catastrophic failures.
This research project will track individual particles and their force skeleton structure that corresponds to the mechanical behaviour via the discrete element method (DEM). This will allow us to track the influence of sand and silt/clay size particles in the overall behaviour.
For engineering practice, the force skeleton structure is quantified by the density of granular materials. For the transition granular materials, the force skeleton structure will be quantified by an equivalent density state (EDS). The EDS will be combined with evolution particle fabric to develop a constitutive model for hydromechanical behaviour.
Join a dynamic team within geotechnical research comprised of world-class researchers and a strong cohort of PhD students. We are currently collaborating with more than 35 local, national and international organisations so you will have ample opportunity to grow your professional and industry network.
What you’ll do
In this project-based research degree, you will carry out both numerical and laboratory research. You will develop a diverse set of skills, conducting advanced triaxial testing, large-scale soil column testing with regular monitoring, and related numerical modelling.
You will perform a series of triaxial and simple shear tests, and then calibrate the model parameters based on the experimental results. Based on the results, you will then propose a new constitutive model for a wide range of soils.
The expertise you gain in both numerical programming and laboratory experiment will give you a competitive edge as there are few researchers strong in both fields.
You will be encouraged and supported to travel to a conference to present your research. There may be funding available for other professional development activities.
Where you’ll be based
You will be based in UniSA STEM. We link engineering, mathematics, science, defence, cybersecurity, construction management, environmental science, aviation, information management, information technology, and project management, harnessing the connections across disciplines to bring big ideas to fruition.
Our researchers deliver technical expertise and advice to industry, government and community groups to make commercially viable and sustainable impacts. The Future Industries Institute, Innovation and Collaboration Centre, and Australian Research Centre for Interactive and Virtual Environments all provide consultancy and access to advanced technology.
In an information-rich world, our people think big, combatting problems, testing solutions and making data-driven decisions. Our graduates are entrepreneurs and trailblazers, who design and build the world they want to live in.
