There is a widespread need throughout the Australian transport, defence and construction industries for high performance energy absorption devices. Data from the Australian Transport Safety Bureau show that in 2002 there were 1,715 people killed in 1,525 crashes in Australia. The proposed research will develop advanced techniques for improving crashworthiness of vehicles, roadside barriers and other energy absorption devices. This will lead to significant reductions in injury to people and damage to structures caused by impact; and thus substantial savings for the nation from the enormous costs associated with the fatalities, injuries and structural damages.

This project will improve national capability to optimise power production from wind turbine farms in complex terrain by improving the understanding of the flow regime. By better understanding separated regions and the turbulent structures within these regions power production can be optimised and fatigue risks associated with turbine positioning in complex sites can be reduced. This will improve confidence in wind farm site assessment techniques and consequently reduce economic risks associated with current wind farm viability assessments. By increasing national capacity to generate clean energy stationary energy emissions can be reduced. This project will also deliver high calibre graduates that will be potential future industry leaders.Read moreRead less

High Rate Testing System for Materials and Structures. Human or natural disasters such as terrorist attack or tsunami take place and they have catastrophic consequences, in terms of fatalities and psyche of fear among the population, as well as enormous financial loss. Vehicle accident is another example. In Australia, 1636 people were killed in 1481 road crashes, in 2005 alone.

Vehicle accident is another example. In Australia, 1636 people were killed in 1481 road crashes, in 2005 alone. There is a great demand for research into devising novel materials and structures for optimum performance under such circumstances. The proposed new high rate testing system will significantly advance research in this area. The facility will directly support a range of research projects in material and structural design in military and civil vehicles, aerospace industry and defence.Read moreRead less
Biotransport design for engineering microenvironment in scaffolds. Tissue engineering signifies an exciting opportunity to solve shortage of transplantable tissues. This project targets a critical issue in engineering thick tissue and aims to introduce computational structural optimisation to biotransport problems. The optimal scaffold is expected to create a more desirable microenvironment for better tissue growth.
Time-dependent dynamic, creep and shrinkage response of curved structural members. This project concerns curved structural members, such as bridge beams, that are subjected to dynamic excitation and to concrete shrinkage and creep. Hitherto, unified formulations for the structural behaviour of these members have not been properly developed. The proposal seeks to build on a previous ARC DP of the investigator that produces significant results for static loading, by developing a sophisticated meth ....Time-dependent dynamic, creep and shrinkage response of curved structural members. This project concerns curved structural members, such as bridge beams, that are subjected to dynamic excitation and to concrete shrinkage and creep. Hitherto, unified formulations for the structural behaviour of these members have not been properly developed. The proposal seeks to build on a previous ARC DP of the investigator that produces significant results for static loading, by developing a sophisticated methodology to handle non-static dynamic loading and for shrinkage and creep. It will develop advanced mathematical tools to enable the safe and efficient design of a multiplicity of structures that is of benefit to on and offshore Australian technology.Read moreRead less
Response of Metallic Foam Core Sandwich Panels under Impact and Blast Loadings. Human or natural disasters such as vehicle crashes, terrorist attacks or tsunami take place with catastrophic consequences, including significant loss of life and considerable financial losses. For example, in Australia in 2002 over 1,700 people died as a result of vehicle crashes. Research on new materials composites and novel composite structures for use in vehicles, buildings and other man-made structures will be ....Response of Metallic Foam Core Sandwich Panels under Impact and Blast Loadings. Human or natural disasters such as vehicle crashes, terrorist attacks or tsunami take place with catastrophic consequences, including significant loss of life and considerable financial losses. For example, in Australia in 2002 over 1,700 people died as a result of vehicle crashes. Research on new materials composites and novel composite structures for use in vehicles, buildings and other man-made structures will be undertaken to evaluate their performance under extreme or disastrous conditions. This project will investigate the performance of sandwich panels with a cellular core structure under high impact or blast loading conditions. The findings will be directly applicable to structural design of military and civil vehicles and components for the aerospace industry in order to mitigate the level of impact or blast loading under extreme conditions.Read moreRead less
