Innovative sandwich structures with Prismatic Hexagonal-like form and polymeric foam material are proposed in this project and should lead to better designs for structure and personnel protection. Critical civil infrastructure such as government buildings might be subjected to severe blast/impact loads during their lifetime, which may lead to catastrophic consequences. Therefore, protective techniques are desired to increase the resistance capacity of critical structures against blast/impact loads. The expected outcome is to develop an innovative sandwich structure with new structural forms to mitigate blast/impact loads for better structure and personnel protections.Read moreRead less
Study of Blast Resistance Capacity of Basalt Fibre Strengthened Structures. This project plans to investigate the dynamic response of basalt fibre reinforced polymer (BFRP) reinforced structures against blast loading. Critical infrastructures such as embassy buildings, high-rise building, bridges and defence facilities are intensively targeted by increasing terrorist activities or accidental explosions. BFRP is a promising material for such structures because it is cheaper than carbon fibre and ....Study of Blast Resistance Capacity of Basalt Fibre Strengthened Structures. This project plans to investigate the dynamic response of basalt fibre reinforced polymer (BFRP) reinforced structures against blast loading. Critical infrastructures such as embassy buildings, high-rise building, bridges and defence facilities are intensively targeted by increasing terrorist activities or accidental explosions. BFRP is a promising material for such structures because it is cheaper than carbon fibre and has better physico-mechanical properties than glass fibre. However, there has been very limited study of the effectiveness of BFRP strengthening on structure blast-loading resistant capacities. This project aims to perform numerical and experimental studies to support the development of BFRP applications in strengthening structures against blast loads.Read moreRead less

Pipelines are important structures but are vulnerable to different types of damage. This damage is often associated with pipeline vibration. It is important to control adverse vibrations to reduce the risk of catastrophic damage. This project proposes using sandwich pipe to suppress different sources of vibrations that may be experienced during the lifetime of the pipeline. Analytical, numerical and experimental investigations will be carried out to demonstrate the feasibility of the proposed method. The project aims to develop direct applications for designing pipelines to suppress different sources of vibration and to guarantee the safety of pipelines.Read moreRead less
Development of novel inerter-based damper for platform vibration control. This project aims to develop a novel inerter-based damper to mitigate the excessive vibrations of offshore floating platforms (OFP), which are widely used in the offshore industry for oil exploration. Harsh environmental loads such as wind and waves can induce excessive vibrations to OFPs and endanger their safety and stability. This project aims to develop a novel inerter-based damper that can produce a considerable appar ....Development of novel inerter-based damper for platform vibration control. This project aims to develop a novel inerter-based damper to mitigate the excessive vibrations of offshore floating platforms (OFP), which are widely used in the offshore industry for oil exploration. Harsh environmental loads such as wind and waves can induce excessive vibrations to OFPs and endanger their safety and stability. This project aims to develop a novel inerter-based damper that can produce a considerable apparent mass that is much larger than its physical mass through an amplifying mechanism by translating the linear motion into high-speed rotational motion, which can significantly reduce the mass and cost of the damper. Benefits of the project include more economical and safer OFP designs, which are expected to improve the competitiveness of Australian pillar oil and gas industries.Read moreRead less

This project aims to develop and apply a new route of lump iron ore pre-reduction with hydrogen or H2-enriched gases for ironmaking to minimise CO2 emission from steel production. The route will be built up on the base of H2 reduction kinetics of iron ore and with novel technologies such as CO2 recycle and H2-heating using hot blast, underpinning the hydrogen economy by addressing the environmental concerns in mineral and steel industries. It is not only significant for low-carbon steel production, but also for better fundamental understanding to develop the future zero-emission iron and steelmaking with hydrogen. The project will be very beneficent because it increases the use of lump iron ore and expends Australian export of iron ores.Read moreRead less
High-resolution optical studies of solids nucleation in cryogenic processes. During liquefied natural gas (LNG) production, low concentration impurities can freeze and block the cryogenic heat exchangers at the heart of the liquefaction process. Substantial knowledge gaps exist regarding the kinetics of these solids (i.e. the rate at which they form), especially at the part per million concentrations relevant to LNG. This project, in partnership with ExxonMobil Upstream Research Company, will us ....High-resolution optical studies of solids nucleation in cryogenic processes. During liquefied natural gas (LNG) production, low concentration impurities can freeze and block the cryogenic heat exchangers at the heart of the liquefaction process. Substantial knowledge gaps exist regarding the kinetics of these solids (i.e. the rate at which they form), especially at the part per million concentrations relevant to LNG. This project, in partnership with ExxonMobil Upstream Research Company, will use a proven high resolution optical technique to deliver new insight into solid nucleation and growth kinetics in the high-pressure cryogenic fluids that govern industrial blockage risk. The results will enable energy optimisation to increase liquefaction efficiency as well as tests of innovative blockage-remediation methods.Read moreRead less
