Time-dependent dynamic, creep and shrinkage response of curved structural members. This project concerns curved structural members, such as bridge beams, that are subjected to dynamic excitation and to concrete shrinkage and creep. Hitherto, unified formulations for the structural behaviour of these members have not been properly developed.

This project concerns curved structural members, such as bridge beams, that are subjected to dynamic excitation and to concrete shrinkage and creep. Hitherto, unified formulations for the structural behaviour of these members have not been properly developed. The proposal seeks to build on a previous ARC DP of the investigator that produces significant results for static loading, by developing a sophisticated methodology to handle non-static dynamic loading and for shrinkage and creep. It will develop advanced mathematical tools to enable the safe and efficient design of a multiplicity of structures that is of benefit to on and offshore Australian technology.Read moreRead less

Design of compliant structure systems with integrated actuators. This project will meet some key scientific challenges in finding new smart compliant structures with desired functions for products, like morphing wings, piezoelectric-based energy harvesters, bio-sensors, in aerospace, energy, medical instruments and environment industries etc., and hence support economic activities and growth in Australia.
Understanding multi-scale reinforcement of carbon fibre composites. Addition of nano scale entities, such as nanotubes, on the surface of a carbon fibre forms a bottle-brush like architecture and strengthens fibre-matrix interface. This project will pioneer development of a systematic approach for analysis and design of such multi-scale reinforced composite materials for use in aerospace and civil industries.
