This project plans to investigate a novel approach for in situ measurement of stress in structures based on an internal resonance phenomenon for nonlinear guided waves. Monitoring the stress level of critical structural components is important to ensure structural safety. The project plans to derive the requirements for this internal resonance and its dependence on stress analytically and verify them experimentally for both simple waveguides and more realistic structures. The expected outcome is the demonstration of the feasibility of a new inexpensive method for continuous monitoring of applied or thermally-induced stresses, which is of great importance in several engineering contexts, such as modern railway track rails, pipelines or pre-stressed strands in concrete structures.Read moreRead less

Understanding multi-scale reinforcement of carbon fibre composites. Addition of nano scale entities, such as nanotubes, on the surface of a carbon fibre forms a bottle-brush like architecture and strengthens fibre-matrix interface. This project will pioneer development of a systematic approach for analysis and design of such multi-scale reinforced composite materials for use in aerospace and civil industries.

Performance enhancement of tidal turbine arrays. This project aims to understand the environmental impact of turbines, by studying how an optimised array of turbines interacts with the downstream turbulent tidal flow. Tidal power could contribute substantially to Australia's Renewable Energy goals. Australia's coastlines produce over 2.4 terajoules of tidal energy, and research into turbine optimisation, array design and environmental impact is needed to exploit this potential. Fluid dynamics and optimisation researchers will design an improved vertical axis tidal turbine for use in the Torres Strait Islands. This project could improve tidal turbine design and turbine placement designs, and improve understanding of interactions between turbines and the maritime environment.Read moreRead less

This project aims to investigate the flow transition from laminar to turbulent in the wake of a circular cylinder subjected to steady current. The project expects to generate new knowledge on the complicated flow behaviours and physical mechanisms for flow transition to turbulence through advanced numerical modelling. Expected outcomes include a physical understanding of the flow evolution to turbulence, as well as an understanding of the laminar and turbulent flow characteristics and the suppression of turbulence in the context of flow control. The knowledge generated will be applicable to improved design and safe operations of the sub-sea transmission and communication cables used in the offshore oil and gas industry and the emerging offshore renewable energy industry.Read moreRead less
An energetic approach to characterise fracture of soft matter by cutting. Cutting of soft materials is a common daily life experience (e.g. slicing of meat and cheese) and an essential operation in many industries, healthcare (e.g. surgery) and manufacturing (e.g. paint removal) among them. By measuring the cutting forces of the tool and examining the deformation mechanisms of the work-piece, this project aims to put the cutting process on a strong scientific and technological footing.

Cutting of soft materials is a common daily life experience (e.g. slicing of meat and cheese) and an essential operation in many industries, healthcare (e.g. surgery) and manufacturing (e.g. paint removal) among them. By measuring the cutting forces of the tool and examining the deformation mechanisms of the work-piece, this project aims to put the cutting process on a strong scientific and technological footing. It provides an ingenious method to measure the fracture energy, i.e. specific resistance to cracking, of plastics, bulk and thin film polymer nanocomposites at different cut-depths. New knowledge gained from the project is expected to improve tool design and optimise cutting conditions to increase the cutting process efficiency.Read moreRead less
The elusive upper bound of heat transfer in horizontal convection. The question as to whether lateral variation in global ocean buoyancy resulting from low solar radiation near the poles and higher temperatures in the tropical regions (known as horizontal convection) is a driver for global ocean currents is critical to our understanding of this complex and delicate system that maintains Earth's temperate climate. This question hinges on the relationship between heat transport and strength of buo ....The elusive upper bound of heat transfer in horizontal convection. The question as to whether lateral variation in global ocean buoyancy resulting from low solar radiation near the poles and higher temperatures in the tropical regions (known as horizontal convection) is a driver for global ocean currents is critical to our understanding of this complex and delicate system that maintains Earth's temperate climate. This question hinges on the relationship between heat transport and strength of buoyancy forcing towards global scales; this project proposes a landmark experimental effort supported by detailed simulations to probe the ultimate regime of heat transport in horizontal convection. The project is expected to inform the direction of future ocean and climate modelling efforts to the benefit of humanity.Read moreRead less

Recent studies reveal that alternating electric or magnetic fields can rotate conductive nanofillers in polymers. This project aims to advance a new concept of aligning nano-scale reinforcements (for example, graphene nano-sheets and carbon nanofibres) along the thickness direction of composite materials. The alignment of nano-sized reinforcement will address the perennial problem of through-thickness weaknesses of fibre-reinforced composites and, at the same time, improve the electrical conductivity of composites. The synergistic improvements in the mechanical and electrical properties will improve damage tolerance and diagnosis of composites, thus expanding their applications in transport and civil construction to help reduce carbon dioxide emission.Read moreRead less
