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

Summary
Research Network for Rehabilitation of Structures Using Advanced Materials and Frontier Technologies. There is an urgent need to rehabilitate existing structures that are considered inadequate in strength and serviceability. Frontier strengthening technologies (such as external post-tensioning and plate bonding) using conventional and advanced materials are being currently developed in Australia by different groups, but as yet not in a coordinated manner. The aim of this network is to bring tog ....Research Network for Rehabilitation of Structures Using Advanced Materials and Frontier Technologies. There is an urgent need to rehabilitate existing structures that are considered inadequate in strength and serviceability. Frontier strengthening technologies (such as external post-tensioning and plate bonding) using conventional and advanced materials are being currently developed in Australia by different groups, but as yet not in a coordinated manner. The aim of this network is to bring together a multi-disciplinary team with complementary strengths to provide an integrated solution for rehabilitation of structures. The core of the network focuses on design tools, linking the various technologies to provide appropriate rehabilitation and understanding of life cycle demands for major infrastructure.Read moreRead less

Fibre Reinforced Polymer (FRP)-Confined Concrete-Encased Steel Composite Columns. 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 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 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
De-consolidation and Re-consolidation of Advanced Thermoplastic Matrix Composites. The project provides a comprehensive physical understanding on thermal de-consolidation and re-consolidation processes in advanced thermoplastic composites during re-heating/cooling processes, such as thermoforming and joining. Mechanistic models based on theoretical analysis, experimental studies and computational modelling will be established to provide a unified approach to predict de-consolidation and re-conso ....De-consolidation and Re-consolidation of Advanced Thermoplastic Matrix Composites. The project provides a comprehensive physical understanding on thermal de-consolidation and re-consolidation processes in advanced thermoplastic composites during re-heating/cooling processes, such as thermoforming and joining. Mechanistic models based on theoretical analysis, experimental studies and computational modelling will be established to provide a unified approach to predict de-consolidation and re-consolidation processes. Optimum processing-windows will be established, with which the undesired deterioration in material meso-structures and mechanical performance due to de-consolidation is effectively minimised. The outcomes of the project will fill the gap in the knowledge for thermoplastic composite processing and will improve the integrity of thermoplastic composite structures in practical applications.Read moreRead less
Design of Novel Metamaterials Considering Large Deformation and Plasticity. 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.

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
