EXPERIENCE:

Graduate Research Assistant at UNC Charlotte, NC, USA (Materials Modelling Laboratory) Aug 2015 - May 2017

Master’s Thesis: Thermal Analysis of filler reinforced polymeric composites to improve thermal conductivity.

ABAQUS and Python Scripting was used for modelling the composite material using carbon nanotubes, Aluminum oxide and zinc oxide fibers.

Python scripting and ABAQUS Macros was used for parametric analysis of the reinforced polymer.

FEM validation with Analytical Homogenization schemes like Mori Tanaka and Maxwell Garnett approximations.

Analyzed for the time dependent response of fiber reinforced polymers using ABAQUS and Python under thermal conduction and effects of thermal stresses/stress concentrations at the interfaces were studied.

PROJECT HIGHLIGHTS

• Structural Analysis and Topology Optimization of Compressor Connecting Rod (ANSYS, Optistruct)

- Static and Transient structural analysis was performed using ANSYS and high stress zones were determined.

- Mesh convergence study was performed and structural errors were removed to interpret the results.

- Fatigue life was calculated using nCode Design Life by stress life approach (S-N) and strain life approach (E-N)

- Optimization for weight and material reduction and stress reducing using various methods like sub modeling

(force or displacement) in Optistruct (Hypermesh).

• High velocity Impact analysis of projectile on a reinforced plate (ABAQUS/Explicit)

-Steel ball is used as a projectile and initial velocity is specified

-Johnson-cook material damage criterion was used for the plate failure

-General contact algorithm is used for contact interactions

-Residual velocities were found for different impact velocities.

• Quasi-static non-linear analysis of forming in a metal sheet (Contact analysis) (ABAQUS, Python)

- Blank was modeled as a 2d deformable plane strain model and Punch, blank holder and die as rigid surfaces

- Contact pairs (Surface to surface contact) were used with some coefficient of friction

- Non-linear effects (frictional sliding and inelastic material behavior) were considered during analysis.

- Maximum plastic strain was compared with failure strain to determine tearing.

• Finite Element Analysis of Heat transfer in a composite wall (ABAQUS, Matlab)

- FE analysis for studying heat transfer in a chimney made up of concrete and brick was conducted in Matlab and Abaqus
