The project aims to establish an effective and efficient computational framework for the topological design of novel mechanical metamaterials considering both geometrical and material nonlinearities. This would overcome a formidable bottleneck in practical applications of metamaterials which are mostly based on linear elastic assumptions. The expected outcomes will be a new methodology and an advanced engineering design tool that can be used for the development of new classes of metamaterials with exceptional mechanical properties (eg negative compressibility or negative Poisson’s ratio) over a large strain range. Such novel metamaterials would have many important applications, particularly in biomedical and defence industries.Read moreRead less

This project will establish an effective and efficient computational framework for the topological optimisation of composites whose constituent phases possess significantly different Poisson ratios. In particular, the proposed research will be focused on exploiting the dramatic improvements in functional properties of composites when the Poisson ratio of one of the constituent phases is either negative or near its incompressibility limit. The expected outcomes will be a new methodology and an advanced engineering design tool that can be used for the development of a new class of composites with exceptional properties. Such new composite systems will have many potential applications, particularly in aerospace, defence and medical industries.Read moreRead less

The application of fibre reinforced polymer (FRP) composites in structural rehabilitation is sometimes challenged or opposed due to the limitation of its fire resistance. This project aims to solve the fire resistance problem of FRP in column jacketing work using innovative approaches. The proposed scheme will be developed by using advanced materials and mechanical fastening technology. It can ensure structural serviceability of FRP jackets during a fire. And after the fire, the proposed jacketing scheme is reusable by applying a new layer of epoxy. The project is expected to advance the theory and technologies in structural rehabilitation. It will also provide significant benefits to the construction industry via sustainable construction.Read moreRead less

The project aims to investigate the behaviour of and design hybrid multiple-tube concrete columns, a form of column. These columns allow the use of small circular high-strength steel tubes, readily available in the market, to suit the specific needs of construction projects of various scales. In the column, a durable outer tube made of fibre-reinforced polymer (FRP) composites protects steel tubes, and their high yield stress can be fully exploited through section configuration. The new column is expected to enable wider, safer and more economical use of FRP and high-strength steel, and meet demands for resilient civil infrastructure.Read moreRead less

This project aims to conduct theoretical, numerical and experimental investigations on the mechanism of surface sprayed viscoelastic materials for blast mitigation of structural members in critical and resource infrastructure. The project design is different from traditional designs and aims to achieve protection with a higher efficiency, in a flexible manner and at a lower cost. Therefore, it is worth exploring systemically the development of design methods which are not yet available. The project outcomes intend to be incorporated into design codes for the purposes of improving the civil infrastructure environment subjected to extreme events.Read moreRead less

The infrastructure in Australia and beyond has long suffered from deterioration due to corrosion of steel reinforcement/sections. This project will address this problem by investigating a new form of hybrid columns, namely fibre reinforced polymer confined concrete-encased steel composite columns. The idea of combining a fibre reinforced polymer-confined concrete and a steel section not only makes the column a durable and ductile alternative to steel/concrete columns, but also makes them an efficient method for retrofitting or strengthening deteriorated steel columns. This project will study the structural behaviour of fibre reinforced polymer confined concrete-encased steel composite columns, and develop design methods to pave the way towards their wide practical applications.

This project aims to quantify the development of the long-term (25-100 year) protective effect of calcareous deposits on the marine corrosion of mild steels. This is significant because such steels used extensively in major and very expensive coastal and offshore infrastructure. The project outcomes will improve scientific understanding, including the role of microbiological activity.
