Hanan Farhat, a PhD student from the University of Saskatchewan plans to complete a corrosion study of SMA materials. Hanan has been setting up the equipment and she has done a literature review and preliminary testing. 

The plans for 2012 are to complete the testing, and publish her findings. She has been helped with materials by Dr. Ibrahim Karaman’s group at Texas A&M University/Texas. 

Dr. R.K. Abu Al-Rub has visited Texas A&M University at Qatar and Qatar University where he interacted with several faculty and explored several collaboration activities. These collaborations have results in several projects that are funded through the National Priority Research Program (NPRP) of the Qatar Research Foundation.  These projects are:

  • Multiscale Analysis of Hybrid Micro and Nano Composite Asphalt for Fracture Resistant and Sustainable Pavements, Qatar National Research Fund (QNRF), $1,049,514, 10/15/12 – 10/14/15).

  • Thermal Dilation and Internal Damage of Cryogenic Concrete Utilized for Direct Liquefied Natural Gas Containment, Qatar National Research Fund (QNRF), $1,003,854, 1/15/12 – 1/14/15).

  • Multiresolution Analysis of Dispersion and Interfacial Bond in Carbon Nanofiber/Nanotube Reinforced Concrete for Improved Strength and Fracture Toughness, Qatar National Research Fund (QNRF), $901,104, 1/15/12 – 1/14/15).

  • Modeling of Environmental-Assisted Degradation Processes in Asphalt Mixtures Using Micromechanical and Continuum Damage Theories, Qatar National Research Fund (QNRF), $992,943, 1/15/12 – 1/14/15).

Dr. Abu Al-Rub has engaged in understanding the effects of dispersed micro- and nano-particles’ size effect on the thermo-mechanical properties of advanced high strength steels (AHSS) for the automotive industry. The ideas surrounding the behavior of transformation induced plasticity (TRIP) steels and particle reinforced composites are combined and investigated. Microstructural-based finite element models have been created in order to investigate the effects of dispersed micro ceramic particles with varying volume fractions, sizes, and properties throughout a TRIP steel microstructure. and in order to identify the key mechanisms responsible for achieving simultaneous enhancements in strength and ductility of AHHS. This effort has results in a Master of Science thesis by Sara C. Diaz who is a US citizen:

  • Diaz, S.C., 2012, “Microstructure-Based Computational Modeling of TRIP Steels with Dispersed Particles,” MSc. Thesis, Texas A&M University, College Station, Texas, USA.

Sara has participated twice in the summer short courses organized by IIMEC. These courses helped her significantly in conducting novel research in her MS.
