Dynamic Crushing of Cellular Solids: Deformation Modes and Energy Absorption. Energy absorption behaviour of structures and materials is essential in minimising damage and fatalities caused by accidental collisions. Cellular solids are excellent in this respect. This project aims to systematically investigate the dynamic crushing of two such materials: honeycombs and metal foams. Experimental techniques applicable to these materials will be developed and comprehensive tests will be conducted. St ....Dynamic Crushing of Cellular Solids: Deformation Modes and Energy Absorption. Energy absorption behaviour of structures and materials is essential in minimising damage and fatalities caused by accidental collisions. Cellular solids are excellent in this respect. This project aims to systematically investigate the dynamic crushing of two such materials: honeycombs and metal foams. Experimental techniques applicable to these materials will be developed and comprehensive tests will be conducted. Studies will be made into their dynamic deformation modes and the associated energy absorption behaviour. The findings will extend our conceptual understanding of a class of similar problems and will help to design structures with cellular solids for much improved crashworthiness performance.Read moreRead less
Reducing wear on rotary coal pulverisers. The aim of this project is to develop an understanding of the small-scale flows and particle breakage required to permit optimised redesign of the attrition stage of the 36 coal pulverisers at Gladstone Power Station, which, because of erosive wear, currently have a maintenance budget of $4M per year. CFD-DEM simulation of the air and particle flows will be used to determine particle flow patterns, particle-particle and particle-wall impact energies. Thi ....Reducing wear on rotary coal pulverisers. The aim of this project is to develop an understanding of the small-scale flows and particle breakage required to permit optimised redesign of the attrition stage of the 36 coal pulverisers at Gladstone Power Station, which, because of erosive wear, currently have a maintenance budget of $4M per year. CFD-DEM simulation of the air and particle flows will be used to determine particle flow patterns, particle-particle and particle-wall impact energies. This information will be input to comminution and wear models to predict pulveriser performance and wear patterns. Simulation results will be validated using measurements from scale visualisation and working models.Read moreRead less

Life-time Modelling of Industrial Products for Reuse. Product disposal responsibility has shifted from consumers to manufacturers. Re-use of components is the most efficient strategy for product recovery, which requires reliable methods for assessing the quality and remaining life of used components. The aim of this project is to develop a lifetime model to estimate the remaining life and quality of a used component. This will enable manufacturers to estimate the potential reusability of a compo ....Life-time Modelling of Industrial Products for Reuse. Product disposal responsibility has shifted from consumers to manufacturers. Re-use of components is the most efficient strategy for product recovery, which requires reliable methods for assessing the quality and remaining life of used components. The aim of this project is to develop a lifetime model to estimate the remaining life and quality of a used component. This will enable manufacturers to estimate the potential reusability of a component without going through costly and time consuming disassembly processes. In addition, the data from the lifetime monitoring process will provide information for improving the design and manufacture of environmentally friendly products.Read moreRead less

A new abrasive waterjet milling technology and process models for fabricating energy-efficient electrical machines from amorphous magnetic metal laminations. As the most energy-efficient core material for electrical machines, amorphous magnetic metal (AMM) can save more than 36% of the energy wasted by ordinary electrical motors. Since electrical motors consume about 70% of all the electricity generated, if all electrical motors in Australia use AMM as the core material, an annual energy saving ....A new abrasive waterjet milling technology and process models for fabricating energy-efficient electrical machines from amorphous magnetic metal laminations. As the most energy-efficient core material for electrical machines, amorphous magnetic metal (AMM) can save more than 36% of the energy wasted by ordinary electrical motors. Since electrical motors consume about 70% of all the electricity generated, if all electrical motors in Australia use AMM as the core material, an annual energy saving worth approximately $4 billion and an annual reduction of 16 million tonnes of greenhouse gas emission in Australia are expected based on the predicted electricity consumption in 2010. This project will develop a new technology for fabricating larger electrical machines from AMM laminations. It targets the national research priorities in Frontier Technologies and An Environmentally Sustainable Australia.Read moreRead less

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
