Research Overview
Using nanomaterials and nanoscale design of materials
in practical engineering applications is my research goal. To realize
the goal, a thorough understanding of structural mechanics at the nanoscale
is essential. Molecular simulations play an integral role in my research.
I use molecular statics and dynamics to study structural mechanisms at
the nanoscale. Multifunctional materials like shape memory alloys and
piezo-electric crystals also interest me. Current molecular simulation
methods though useful pose many limitations. Developing new
molecular simulation techniques for engineering applications is another
aspect of my research.
For my masters' thesis, I used nanoclay to enhance the mechanical properties of polymers and polymeric composites. I developed manufacturing methods to add nanoclay in conventional composites. Small amounts of nanoclay (5% by weight) increased the elastic modulus and compressive strength of resin significantly (20-40%). Fracture toughness was also increased by 30-40 % by adding nanoclay. Hence I demonstrated that a stiffer, stronger and tougher composite can be produced by using nanoclay.
Most of my research is done in the Composites Materials Laboratory at the school of Aeronautics and Astronautics, Purdue University.
