High-order conservative multiscale computation of elliptic problems in composite materials and porous media. The proposed technology will improve the design and performance of a wide range of mechanisms and industrial processes involving heterogeneous media, from composite materials to water filtration and recycling. Our researchers in computational mechanics will gain further opportunities to extend the advances this project will make.
Effective and accurate model dynamics, deterministic and stochastic, across multiple space and time scales. A persistent feature of complex systems in engineering and science is the emergence of macroscopic, coarse grained, coherent behaviour from the interactions of microscopic agents (molecules, cells, grains) and with their environment. In current modeling, ranging from ecology to materials science, the underlying microscopic mechanisms are often known, but the closures to translate microscal ....Effective and accurate model dynamics, deterministic and stochastic, across multiple space and time scales. A persistent feature of complex systems in engineering and science is the emergence of macroscopic, coarse grained, coherent behaviour from the interactions of microscopic agents (molecules, cells, grains) and with their environment. In current modeling, ranging from ecology to materials science, the underlying microscopic mechanisms are often known, but the closures to translate microscale knowledge to a system level macroscopic description are rarely available in closed form. Our novel methodology will explore this stumbling block, and promises to radically change the modeling, exploration and understanding of multiscale complex system behaviour.Read moreRead less

This project will produce novel mixed ionic and electronic conducting cathodes to reduce the operating temperature of solid-oxide fuel cells (SOFC). The technology developed is of ultimate benefit to the Australian electricity consumer. It can accelerate the development of low-cost SOFCs that can serve in distributed power generation. The benefits include increased reliability of the power supply and substantive cost savings through increased efficiency of the conversion of gas to electricity. Depending on the level of market penetration, the broad deployment of SOFCs can save well over $100 million/year for the Australian consumer. The environmentally friendly technologies will also be beneficial for reducing pollution and greenhouse gases in Australia.Read moreRead less

Australia has exceptional quality and depth in photon science research, with a demonstrated capacity to found and grow commercial ventures. However, the optimal design of interconnections in a photonic package is severely restricted by a lack of detailed knowledge of their deformation and failure mechanisms. The proposed study will use novel techniques to create a basis for mechanism-based deformation and failure models that will then be used to improve the design and lifetime of new type microstructured optical fibres and adhesive assemblies, expanding and enhancing Australia's capacity in the areas.
