Crack Propagation within Graded Interfaces. Functionally graded interfaces are a technologically new way of joining materials in a wide range of biomedical and industrial applications. The reduction in the interfacial stresses resulting from the graded interface increases the structural integrity of the component, however, existing models do not fully address issues of plasticity and cyclic fatigue to their fracture. The intention of this study is to investigate how modifications to the ductil ....Crack Propagation within Graded Interfaces. Functionally graded interfaces are a technologically new way of joining materials in a wide range of biomedical and industrial applications. The reduction in the interfacial stresses resulting from the graded interface increases the structural integrity of the component, however, existing models do not fully address issues of plasticity and cyclic fatigue to their fracture. The intention of this study is to investigate how modifications to the ductile reinforcement phase and how the cyclic loading influence crack extension within a graded interface. These results will assist in future design and prediction of the in-service lifetime of components containing gradient interfaces.Read moreRead less

Radiative cooling offers a means to cool buildings sustainably without complex and costly heat pumps or air conditioners. Units similar to solar panels can be designed with surfaces which radiate mostly into the 8 - 12 micron atmospheric window, which has a radiance much less than for other wavelengths. Commercial development has been limited by problems associated with the degradation, performance or cost of radiator surfaces. This project seeks to improve both performance and durability with innovative use of alternative materials and sputtered coatings suitable for mass manufacture, and to test the outdoor performance of laboratory produced radiative plates.Read moreRead less

Structures and properties of tissue engineering matrices for cartilage and bone: Imaging, visualising and modelling tissue/scaffold constructs in 3D. Tissue engineering of bone and cartilage has the potential to lower costs and improve outcomes. The first stage requires the design of porous 3D scaffolds.

Tissue engineering of bone and cartilage has the potential to lower costs and improve outcomes. The first stage requires the design of porous 3D scaffolds. To date they have been found less than ideal for clinical applications. Our ability to design and optimise scaffolds has been ad hoc, as local structure and properties have not been measurable during tissue growth and repair. In this proposal, an interdisciplinary group from three universities will utilise microCT imaging, visualisation and numerical modelling to determine these structures and properties. This will provide an invaluable understanding for the further development of tissue engineering scaffolds.Read moreRead less
