1Overview and background Mohammad SaadatfarDepartment of Engineering, The Australian National University
2Research School of Physics & Engineering ANU College of Physical and Mathematical Sciences
3School Structure• The largest university based physics research activity in Australia• ~ 170 full time academic staff~ 150 graduate students~ 110 technical and administrative staffFull undergraduate teaching program (3-4 years)9 Research Departments
4Dept. Applied Mathematics Founded by Prof Barry Ninham in 1971Chemists, physicists, mathematicians and engineersTheoreticians and experimentalists working togetherWhat shapes matter?How does matter interact?Complex and hierarchical (multiscale)Fields: geometry and topology in nature, molecular force measurement, nanomaterials, packing in granular materials and flow in porous materialsApplications : biomineralisation, composite materials, adhesion, oil & gas, printing and paper making, wood, mineral processing, crystallographic theory, textiles, osteoporosis…..
5i. Granular materials ii. Elasticity of sandstones My PhD research:A combination of experimental and numerical study the following topics:i. Granular materials ii. Elasticity of sandstonesiii. Mehcanical and transport properties of polyurethane foams.I developed a series of Finite Element codes for fluid and elasticity simulation. All codes developed during my PhD have now been integrated into Mango (3D image processing toolkit)Post PhD: sine PhD in 2006, my research has been focused on metallic foams, rock physics and granular materials using tomography. I worked as a postdoc and/or visiting researcher in Germany/UK/Ireland/France.I returned to ANU in 2009 and started my independent research on granular materials. Currently I am leading a small group comprised of a postdoc + three PhD students and a technician.The result of my research has been published in over 30 journal publications and over 10 conference proceedings.
6Industry collaboration Digicore Consortium: I am a part of a core team of 12 people running the Digicore Consortium, which is the largest Oil/Gas Consortium in Australia, bringing over $8M funds to ANU over the last 8 years, and was the basis of the spin-off, Lithicon.FEI: I am a named contributor on the ANU’s contract with FEI, which has recently acquired Lithicon (a spin-off of the Department of Applied Mathematics) for $78M. The ANU contract has two phases; $4M technology transfer and a series of R&D projects for applications development in CT.Adidas: I am currently the lead person in negotiation with Adidas to fund a project aiming to research and improve the performance of cricket bats through the understanding of the role of wood cellular structure in mechanical resilience.ANLEC: Over the past 18 months, a substantial amount of my research has been focused on a project funded by ANLEC, which is investigating CO2 geosequestration.
7Snapshot of my research Grain identification2DEach sample has up to 100,000 GRAINS!!! In space!!!!3D
8Grain/pore partitioning used in pore network representation of rocks Measure grain contact network; find loose vs. well compacted systems. Measure grain coordination number…Can give geologist a comprehensive grain analysis tool.
9Numerical simulations of single phase flow attempting to quantify local changes in flow properties. Visualisation of flow paths within a porous system
10Combining 3D images and fluid simulations Fluid in porous rock
11Research on polymeric and metallic foams ElasticityStructure
12Granular materials: used as model systems for unconsolidated rocks to better understand their mechanics and localised phenomena such asstress/strain localisation and shear banding.
