Mathematical and mechanical modeling of nano particulate flow. Nano particulates are the basis for many new technologies, including coatings in the electronics industry, composite materials and medical and pharmaceutical applications.

Nano particulates are the basis for many new technologies, including coatings in the electronics industry, composite materials and medical and pharmaceutical applications. Worldwide industrial competition is increasingly determined by our capacity to handle such highly cohesive materials, and to exploit their novel physical, chemical and mechanical characteristics. Devising handling mechanisms and understanding nano particulate flows depends on formulating accurate mathematical models which reflect the correct underlying physics. This APF proposal will utilise advanced continuum mechanics to develop the correct underlying conceptual ideas to resolve fundamental nanomechanical particulate flows, which will lead to the next generation of engineering tools.

The proposed research will provide our local construction and mining industries with a much needed fast and low cost technology for geotechnical investigation of very large sites which is currently not available. The project will help steer Australia to the forefront of ambient noise research for geotechnical site investigation, in the characterisation of unsaturated compacted soil and in the determination of dynamic site characteristics which are required for seismic risk assessment. Two postgraduate students will benefit from this research by receiving research training at the highest level and it will also pave the way for exporting the technology developed overseas, particularly to our near neighbours in Asia and the Pacific.

Assessment and Prediction of Particle Breakage under Cyclic Loading. Every year, transport industries spend millions of dollars to maintain existing tracks suffering excessive settlement due to heavy traffic. In railways, differential settlement and track fouling are mostly due to ballast breakage. Frequent maintenance requires large amounts of quarried ballast causing environmental degradation.

Every year, transport industries spend millions of dollars to maintain existing tracks suffering excessive settlement due to heavy traffic. In railways, differential settlement and track fouling are mostly due to ballast breakage. Frequent maintenance requires large amounts of quarried ballast causing environmental degradation. Simulation of particle breakage subject to cyclic loading is pioneering fundamental research that will have significant impact on the design and maintenance of future rail and road networks. A full understanding of the breakage mechanisms of aggregates will lead to innovative techniques in design and construction, including faster trains carrying heavier loads with reduced maintenance costs.Read moreRead less

The proposed research addresses the fundamental mechanics of contact for a wide range of civil engineering structures such as piles, retaining walls, and soil anchors. Piles and anchors are essential parts of off-shore platforms which, in turn, are key elements of the Australian oil and gas industry.

Such a tool does not currently exist and will result in safer and cheaper geotechnical design. The methods developed in this project can also be extended to study human joints and joint replacements.Read moreRead less
Contaminant Transport in Marine Sediment. Sediments in bays and estuaries are often contaminated. The inorganic contaminants in sediments can be released back into the water body through mass transfer processes. The mass transfer rate is largely controlled by the wave-driven seepage flux across the seabed. Quantification of this flux is thus a key factor in modelling water quality of coastal water bodies. This project aims to: (1) develop models forwave-induced seepage flux within sediments and ....Contaminant Transport in Marine Sediment. Sediments in bays and estuaries are often contaminated.

Breakwaters are central to the economies and lifestyles of many coastal areas around the world. The liquefaction of breakwater foundations causes the failure of breakwaters, with potentially deliterious consequences for life and property. The remedies involve large investments in maintenance and cause major disruptions to coastal activities. More accurate and reliable methods for analysing the stability of structures and their foundations is urgently required, and will bring major benefits to Australian coastal facilities.
