The proposed research is a fundamental investigation of the compressive mechanical properties and failure mechanisms of fibre reinforced polymer (FRP) composites reinforced with z-pins. These composites are a new material with strong potential applications in aerospace structures subject to high compressive loads, however their compressive properties are poorly understood.

Prediction of Time-dependent Deformations in Post-tensioned Concrete Suspended Slabs in Tall Buildings. The proposed project aims to develop an analytical model that can predict the time-dependent deformations in post-tensioned concrete slabs considering concrete shrinkage and creep, cracking, and bond-slip behaviour. Over the past several years, numerous cases have been reported in Australia and elsewhere, of flexural elements for which the calculated deflection is far less than the actual defl ....Prediction of Time-dependent Deformations in Post-tensioned Concrete Suspended Slabs in Tall Buildings. The proposed project aims to develop an analytical model that can predict the time-dependent deformations in post-tensioned concrete slabs considering concrete shrinkage and creep, cracking, and bond-slip behaviour. Over the past several years, numerous cases have been reported in Australia and elsewhere, of flexural elements for which the calculated deflection is far less than the actual deflection leading to serviceability problems. The significance of this investigation hence lies in its potential to provide a solution to more accurately predict service-life deflections in post-tensioned concrete suspended slabs and validate the model with real-life deflections monitored over time on a current building project.Read moreRead less

Developing new, water-based lubricants for sheet metal forming. There is increasing pressure on manufacturers, including the sheet metal forming industry, to use less toxic, water-based lubricants with a number of common additives being banned or being phased out internationally. In the case of automotive manufacturers, this is combined with demand for alternative sheet materials to reduce costs or cater for export markets.

There is increasing pressure on manufacturers, including the sheet metal forming industry, to use less toxic, water-based lubricants with a number of common additives being banned or being phased out internationally. In the case of automotive manufacturers, this is combined with demand for alternative sheet materials to reduce costs or cater for export markets. Efficient development of new lubricants or replacement additives requires a comprehensive understanding of the interactions between lubricant components and the surface of the sheet metal. This project will explore and model these interactions and how they are affected by the variables in a metal forming process.Read moreRead less
