Next generation nondestructive inspection using guided-wave mixing. This project aims to develop a novel approach for early damage detection. It relies on a systematic experimental investigation of nonlinear ultrasonic interaction between different input wave modes in the presence of damage, so as to identify optimal mode selections and operating parameters that will maximise the sensitivity to particular forms of structural damage.

This project aims to develop a novel approach for early damage detection. It relies on a systematic experimental investigation of nonlinear ultrasonic interaction between different input wave modes in the presence of damage, so as to identify optimal mode selections and operating parameters that will maximise the sensitivity to particular forms of structural damage. The effects of in-service loading on wave-mixing response, and non-contact detection suitable for hard-to-inspect surface conditions, will also be investigated. The new developments will help transform existing schedule-based maintenance practice to a condition-based maintenance paradigm, to achieve significant cost savings in maintenance.Read moreRead less
Finite element and optimization methods for creating complex structure in additive manufacturing. Additive manufacture based on five-axis focused ion beam is a novel manufacturing technology, which has some outstanding properties such as low pollution, no machining, net shape, high efficiency, and high precision characteristics. It produces much less waste as it adds materials, rather than subtracting. This project focuses on developing powerful finite element and topology optimisation method fo ....Finite element and optimization methods for creating complex structure in additive manufacturing. Additive manufacture based on five-axis focused ion beam is a novel manufacturing technology, which has some outstanding properties such as low pollution, no machining, net shape, high efficiency, and high precision characteristics. It produces much less waste as it adds materials, rather than subtracting. This project focuses on developing powerful finite element and topology optimisation method for analysis and design of complex structures in five-axis focused ion beam (or direct laser rapid sintering) based additive manufacturing. The success of this project may benefit Australian manufacturing industry for promoting and developing this emerging and disruptive technology.Read moreRead less

A low-temperature scanning tunnelling microscope: The project aims to establish a facility to exploit the spectroscopic and spatial resolution of an ultra-low temperature scanning tunnelling microscope in conjunction with atomically controlled dopant engineering. In a variety of experiments the research team will explore ultra-scaled transistors, quantum information science devices, and engineered quantum matter. Improving our ability to investigate semiconductor materials at the atomic scale impacts fields ranging from electronics, telecommunication, quantum information to renewable energy research and puts Australia at the forefront of the field of controlled atomic systems in semiconductors.Read moreRead less
