1. Finite
Element Modeling (FEM) of thermoelectric phenomena in electric field activated
sintering
Developed finite element model to quantify the conduction of electric
current through sintering compacts and resultant temperature field. Optimized
field processing conditions to provide manufacturing benefits.
2. Discrete Element Modeling (DEM) of thermoelectric phenomena
in electric field activated sintering

3. Modeling of anisotropy of effective thermal conductivity due
to compaction
Discrete Element Modeling of effective thermal conductivity of compact
evolution via isostatic and close-die compactions.
4. Atomistic simulation of physical properties of Noble gas
Developed a Noble Gas Simulator - a C++ program simulating the behavior
of Noble gas under different temperatures using atomistic simulation.
Developed the codes to simulate the annealing of Noble gas using Molecular
Statistics, Molecular Dynamics and Monte Carlo with Lennard Jones pair
wise potential function. Calculated physical properties (specific heat,
radial distribution function, stress tensor) in the assembly.
5. Molecular Dynamics (MD) simulation of sintering of nanoparticles
Incorporated the effect of electron wind force into the Molecular Dynamics
algorithm. Developed the codes to simulate the sintering of copper under
electric field using Molecular Dynamics with Embedded Atom Method (EAM).
6. Modeling of composite material structure
Joined SAMPE(r) 6th Annual Super Light-Weight Composite Bridge Building
Contest organized by Society for the Advancement of Material and Process
Engineering (SAMPE). Developed finite element model for honeycomb composite
bridge. Investigated the effect of carbon fiber enforcement in bridge
design. Optimized design by identifying the potential failure modes.
