Summary
Dynamic Fracturing and Energy Release Mechanisms in Heterogeneous Materials. The prediction of fracturing behaviour in geomaterials (i.e. rock, soil and concrete) under dynamic/impact loads is essential in dealing with a wide range of engineering problems including excavation and mining, blasting and fragmentation, earthquake engineering, impact cratering, and protective structure design However, current knowledge and modelling capabilities of these applications remains empirically based. This p ....Dynamic Fracturing and Energy Release Mechanisms in Heterogeneous Materials. The prediction of fracturing behaviour in geomaterials (i.e. rock, soil and concrete) under dynamic/impact loads is essential in dealing with a wide range of engineering problems including excavation and mining, blasting and fragmentation, earthquake engineering, impact cratering, and protective structure design However, current knowledge and modelling capabilities of these applications remains empirically based. This project aims to investigate fundamental issues governing the dynamic fracturing of geomaterials and apply this knowledge to advance the understanding and modelling capacity of dynamic fractures in geomaterials.Read moreRead less
Engineering screw piles to secure offshore wind energy turbines. This project aims to tackle the scientific challenges of using screw piles as foundations for deep water offshore wind turbines. Current foundations for offshore infrastructure developments have reached their limits, and conventional screw piles are designed for land use. This project will use innovative geotechnical methods to develop verified designs, guidelines and numerical tools for predicting the forces required to install sc ....Engineering screw piles to secure offshore wind energy turbines. This project aims to tackle the scientific challenges of using screw piles as foundations for deep water offshore wind turbines. Current foundations for offshore infrastructure developments have reached their limits, and conventional screw piles are designed for land use. This project will use innovative geotechnical methods to develop verified designs, guidelines and numerical tools for predicting the forces required to install screw piles into the seabed and their capacity to resist extreme wind and wave forces relevant to these structures. As foundations cost up to 35% of construction, screw piles will provide significant economic and environmental benefits in reducing costs and unlocking substantial renewable energy from our oceans.Read moreRead less

Summary
Multiobjective optimisation of reservoir operations under uncertainty. This project aims to address a crucial water resources management problem: how to manage reservoirs under uncertainty. This project expects to develop an optimisation-based framework to improve the delivery of water resources from optimised reservoir operational strategies. Expected outcomes include an innovative tool for multiobjective decision-making under uncertainty, and robust operational strategies catering for real-wor ....Multiobjective optimisation of reservoir operations under uncertainty. This project aims to address a crucial water resources management problem: how to manage reservoirs under uncertainty. This project expects to develop an optimisation-based framework to improve the delivery of water resources from optimised reservoir operational strategies. Expected outcomes include an innovative tool for multiobjective decision-making under uncertainty, and robust operational strategies catering for real-world operational situations, including conflicting objectives, natural variability in system inputs, and future uncertainty due to climate change and population growth. The improved decisions will protect lives and assets, and postpone expensive infrastructure upgrades by maximising benefits from current systems.Read moreRead less
Linking microstructural evolutions across the scales of granular failure. This project expects to transform the understanding of granular materials and their behaviour by establishing explicit links between the macroscopic responses of the materials and their evolving microstructural properties. This should lead to revolutionary constitutive models for granular materials that possess true mechanisms of evolving grain-scale structures. The proliferation of these new models should allow developmen ....Linking microstructural evolutions across the scales of granular failure. This project expects to transform the understanding of granular materials and their behaviour by establishing explicit links between the macroscopic responses of the materials and their evolving microstructural properties. This should lead to revolutionary constitutive models for granular materials that possess true mechanisms of evolving grain-scale structures. The proliferation of these new models should allow development of reliable predictive computational tools for the modelling and assessment of field-scale failure involving granular materials, enhancing the capability to assess the integrity and stability of earth structures, and benefitting the Australian economy, environment and public safety.Read moreRead less
Internal soil erosion: from grain-scale insights to large-scale predictions. This project aims to further the understanding of internal soil erosion across different spatial and temporal scales. Internal soil erosion is the most frequent cause of failures of water retaining structures. An approach combining advanced X-ray techniques with particle based methods will be developed to observe, analyse and link different material properties and external conditions governing the erosion process. This ....Internal soil erosion: from grain-scale insights to large-scale predictions. This project aims to further the understanding of internal soil erosion across different spatial and temporal scales. Internal soil erosion is the most frequent cause of failures of water retaining structures. An approach combining advanced X-ray techniques with particle based methods will be developed to observe, analyse and link different material properties and external conditions governing the erosion process. This will lead to better criteria for soil erosion and numerical tools for field scale failure analysis and risk assessments. The expected outcomes of this project include enhanced capability to assess the integrity and stability of earth structures and better design criteria against erosion.Read moreRead less
