Damage micromechanisms in alumina hybrid bilayers with graded interfaces. This project proposes a new design concept for high performance alumina hybrids with graded interfaces. The key to this process is the incorporation of thin graded interfaces between an outer homogeneous alumina layer for strength, hardness and wear resistance, and an inner heterogeneous alumina hybrid layer for damage tolerance. The project will explore unresolved issues concerning the effect of graded interfaces on the f ....Damage micromechanisms in alumina hybrid bilayers with graded interfaces. This project proposes a new design concept for high performance alumina hybrids with graded interfaces. The key to this process is the incorporation of thin graded interfaces between an outer homogeneous alumina layer for strength, hardness and wear resistance, and an inner heterogeneous alumina hybrid layer for damage tolerance. The project will explore unresolved issues concerning the effect of graded interfaces on the failure micromechanisms. Advances in this area will provide new strategy or insights for designing novel next generation layered materials.Read moreRead less
Determination of the Properties of Hyper-Elastic Materials by Deep Indentation. We seek to develop the scientific basis for the interpretation of the results of "deep" indentation testing of non-linear elastic (hyper-elastic) materials. Simple tests (such as indentation) produce complex strain fields. Interpretation of the resulting data in terms of stiffness, for example, requires a complex model of the deformation process that can be utilised to link the observed behaviour to the basic prope ....Determination of the Properties of Hyper-Elastic Materials by Deep Indentation. We seek to develop the scientific basis for the interpretation of the results of "deep" indentation testing of non-linear elastic (hyper-elastic) materials. Simple tests (such as indentation) produce complex strain fields. Interpretation of the resulting data in terms of stiffness, for example, requires a complex model of the deformation process that can be utilised to link the observed behaviour to the basic properties of interest. This project is dedicated to an understanding of the complex deformation associated with large strain indentation of hyper-elastic materials and structures, development of finite element based models for this deformation and creation of techniques for interpretation of the results of such indentation tests.Read moreRead less

With the aging of our population, issues concerning the lifetime of biological system are paramount to the quality of life and economic well being of our society. This project is closely linked to the development of prosthetic materials and structures that will improve performance and life of biomechanical devices, by providing better understanding to the mechanics of failure and failure origins of ceramic-based dental crowns and restorations, and to develop materials that will withstand exacting conditions - in body fluids - over extended lifetimes. Crown replacement is by far the most widespread of all prosthetic procedures. This project promises to help bridge the gap between physical and medical science in Australia. Read moreRead less

Australia has vast resources of unconventional oil/gas, which require hydraulic fracturing to stimulate production. This project aims to develop advanced low-density high-performance proppants from industry waste for hydraulic fracturing. This will be achieved by selecting purer SiO2 raw material, carefully designing the porous structure, and fully understanding its relationship with strength and pack conductivity. Low-density means no chemicals in proppant transportation and application. Successful development of such high-performance proppants will significantly increase Australia oil/gas exploration and production with an environmental acceptable technology, a leap forward for the oil/gas industry in Australia and the world.Read moreRead less

Evolution of Contact Damage in Layer Structures. Brittle layer structures (eg brittle coating on ceramic substrate) can be much more damage tolerant than their constituent material components - cracks tend to remain contained within the coating. Very little is known about the factors that control this behaviour.
