Recent research at the University of Sydney has shown that the local and distortional buckling modes in thin-walled high strength steel sections may have adverse interaction. Cold-Formed steel sections of this type are used in residential construction, ceiling systems, partitioning systems in offices and other light gauge applications. The project will develop mathematical models of the interaction behaviour of sections of this type for a wide range of section geometries. A major outcome will be design methods which accurately quantify the interaction behaviour based on the models. Testing will be undertaken to support the theoretical developments and to calibrate the design models.Read moreRead less

An exciting class of materials has emerged with grain sizes two orders of magnitude finer than that produced by conventional processing. These nanocrystalline alloys are produced by intense plastic straining termed equal channel angular extrusion (ECAE). The aim of the project is to incorporate novel experimental techniques, using single crystals, in situ annealing and 3-D computer simulation to develop a fundamental understanding of microstructural stability during ECAE and subsequent thermal treatment. Such advances in our understanding of boundary mobility in fine-scale microstructures is important for evaluating their stability and, hence, the possible commercial exploitation of these materials.Read moreRead less

Advances in modern technology and a competitive manufacturing industry depend critically on new and improved materials. The pace of change is rapid, and many countries are taking steps to improve and coordinate developments. Australia has a very successful record of materials research and innovation and is developing a substantial infrastructure in the area. However, the materials research community is scattered, and research effectiveness is sometimes lessened by a lack of critical mass. This network will bring together university, government and industry researchers, and promote collaborative research, access to each other's facilities, staff and student exchanges, improved access to existing infrastructure and coordinated planning for new acquisitions.Read moreRead less
