PROFESSIONAL EXPERIENCE

Graduate Research Assistant at Computational Solid Mechanics Lab, UF Summer 2011-Fall 2012

Research: Rolling Contact Fatigue (RCF) Simulation of Ball Bearing's material M50Nil.

Studied Classical Contact Mechanics and the relation between Indentation Hardness and Yield

Strength of Plastically Graded Materials (PGM's) M50Nil mainly under RCF condition.

Performed Non-linear Finite Element Analysis of Rolling Contact Fatigue(RCF) in Abaqus/CAE and

validated results by analytical solutions and hand Calculations.

Sub modeled the whole model in Abaqus to test the Plastic Zone.

Inserted different size and shape Carbide particles and studied their interaction in Plastic Zone to test

for Ratcheting behavior of the bearing material (M50Nil) under cyclic loading conditions.

ACADEMIC PROJECTS

Non Linear Finite Element Analysis of Deep Drawing Process of Sheet metal

3D modeling consisting die, punch & blank holder, in Abaqus 6.11 using Elastic-Plastic material with

Isotropic Hardening model and three steps simulation done using 3D Solid & Shell elements.

Studied the deformed shape plots at max. punch stroke, contour plots of effective plastic strain,

variation of thickness of blank and comparison of Solid and Shell elements for different binder forces.

Simulation of the Closure of the Engine Gasket and Design and Optimization of the Gasket Shape

Performed nonlinear finite element analysis for initial geometry of the gasket with material

parameters that are determined using Mooney-Rivlin, 2nd-order polynomial & Ogden models and

convergence analysis to determine a reasonable mesh size.

Modified the design of Gasket reducing gap & making contact pressure as uniform as possible.

Design of Ceiling Fan in Solid Works

Modeled and Assembled Ceiling Fan components using design features such as Extrude, Revolve,

Sweep, Blend, Loft, Swept, Blend, Shell, Spline etc. in Solid Works.

Studied theory and equations behind all the features used.

Design and Optimization of Graphite-Epoxy Laminate Composite

Designed a Cylindrical Fuel tank of Lockheed Martin X-33 space plane using Graphite-Epoxy

composite laminates for the lightest balanced and symmetric laminate which can safely withstand

given state of stress & failure criteria using optimization tools Microsoft Excel Solver and MATLAB.

Designed & optimized plate thickness & orientation angle for max. fundamental vibration frequency.

Prediction of direction of propagation of crack under mixed mode of fracture

Analyzed Center Crack in an infinite plate subjected to both Normal as well as Shear Stress .

Studied crack branching angle as a function of mode-mixity parameter using several criterion.
