Finite Strain with large rotations: A new hybrid numerical/experimental approach. Deformation up to large strains and rotations is important in rocks, metals, polymers, and biomaterials. Computational mechanics is a standard tool for modelling such deformations. However, in earth sciences, mechanical theories use small-strain formulations or large-strain approaches with classical stress rates. Classical stress rates can lead to incorrect stored energies. This project proposes to test a new large ....Finite Strain with large rotations: A new hybrid numerical/experimental approach. Deformation up to large strains and rotations is important in rocks, metals, polymers, and biomaterials. Computational mechanics is a standard tool for modelling such deformations. However, in earth sciences, mechanical theories use small-strain formulations or large-strain approaches with classical stress rates. Classical stress rates can lead to incorrect stored energies. This project proposes to test a new large-strain theory tailored to rocks experimentally, and to apply it to a pivotal geological problem: shear zone formation. The project will advance our fundamental understanding of the mechanics and energetics of rock deformation and provide a novel tool for the modelling of large deformations.Read moreRead less
Assessing and enhancing the resilience of Australian beaches to sea level rise. Accurate forecasting of coastal recession due to sea level rise is required for planning and the design of coastal defences, but the existing method is widely disputed.

Accurate forecasting of coastal recession due to sea level rise is required for planning and the design of coastal defences, but the existing method is widely disputed. With collaboration with world leading research partners, this study will perform unique laboratory experiments to determine the vulnerability of Australian beaches to sea level rise and to test environmentally sustainable measures to increase their resilience. The research will address longstanding uncertainties and significantly enhance the ability of communities to plan for a changing climate. The project will deliver new data and models of immediate benefit to professional engineers to enable robust engineering decisions which enhance the safety of coastal communities.Read moreRead less

The ARC Training Centre for Advanced Technologies in Rail Track Infrastructure aims to transform Australia’s rail construction and maintenance technologies through specialist training of industry-focused researchers. Generation of new knowledge and close collaboration with companies within the rail supply chain will result in enhanced rail capacity and supply chain efficiency across the rail network. This will include increased axle loads and higher speeds, greater safety margins, reduced construction and maintenance costs, and a body of competent railway professionals in the nation’s work force.Read moreRead less
Mega spatial-scale, multi time-scale, ensemble assessment of climate change driven coastal change in South Eastern Australia. Climate change driven variations in mean sea level, storm surges, and waves will change the world's coastline. This project will, for the first time, develop innovative modelling methods to quantify the integrated impact of these climate drivers on coastal erosion along Australia's most developed and populated coastline: Sydney to Brisbane.
Local scour below offshore pipelines on calcareous sediments. This project will improve predictions of erosion around subsea structures in calcareous sediment, allowing potential pipeline self-burial. This will reduce the considerable costs currently spent on pipeline stabilisation and increase the viability of Australia's offshore resources and the competitiveness of the Australian oil and gas industry.
Predicting scour and scour-induced settlement of subsea infrastructure. This project aims to develop improved predictions and understanding of the potential and extent of scour and scour-induced settlement of subsea infrastructure on mobile seabeds. This is expected to enable scour and settlement to be accounted for directly in engineering stability and serviceability design, overturning current practice which ignores both effects on the basis of using scour protection and costly maintenance and ....Predicting scour and scour-induced settlement of subsea infrastructure. This project aims to develop improved predictions and understanding of the potential and extent of scour and scour-induced settlement of subsea infrastructure on mobile seabeds. This is expected to enable scour and settlement to be accounted for directly in engineering stability and serviceability design, overturning current practice which ignores both effects on the basis of using scour protection and costly maintenance and remediation. Development of accurate predictions is expected to be achieved through physical model testing, numerical modelling and analysis of field data. Predictions should improve subsea reliability and lead to omission of scour protection in some situations, increasing international competitiveness of our offshore oil and gas industry.Read moreRead less
Hydrodynamic forces on small diameter pipelines laid on natural seabed. This project aims to improve predictions of hydrodynamic forces on small submarine cables and pipelines through comprehensive experimental modelling at 1:1 scale coupled with development of predictive numerical models. The focus will be on forces in unsteady flows. Present industry guidelines do not make allowance for potential reductions in forces for small diameter pipelines whose diameters are a similar length to the effe ....Hydrodynamic forces on small diameter pipelines laid on natural seabed. This project aims to improve predictions of hydrodynamic forces on small submarine cables and pipelines through comprehensive experimental modelling at 1:1 scale coupled with development of predictive numerical models. The focus will be on forces in unsteady flows. Present industry guidelines do not make allowance for potential reductions in forces for small diameter pipelines whose diameters are a similar length to the effective seabed boundary layer, thereby leading to overly conservative and costly stability design. Results from the experimental program and numerical model developed are expected to be used to improve the current industry design guidelines.Read moreRead less

Such concrete would improve indoor comfort without human intervention and significantly reduce the energy consumed in heating and cooling. TESA concrete is made of porous lightweight aggregate impregnated with phase-change materials. The aim of this project is to investigate and optimise the structural and functional performance of TESA concrete. In particular, it aims to reveal the microstructure, mechanical, thermal, durability properties of TESA concrete and ways to optimise its overall performance. This knowledge would provide a solid foundation for the numerical simulation of TESA concrete and its use in engineering applications.Read moreRead less
Bed shear stress on beach sediment and coastal structures under wave run-up. The aim of this work is to obtain critical new information about the way waves interact with the coast and the damage they can cause to beaches and coastal protection structures. This new data will provide the basis for improved predictions of coastal erosion and better coastal engineering design in the face of sea-level rise and climate change.
