WORK EXPERIENCE:


v Graduate Research Assistant, July 2007 – July 2010

Composite Lab, TheUniversity of Alabama, Tuscaloosa, AL

 

Duties andResponsibilities:

Jobresponsibility includes material and mechanical properties characterization,and life prediction of polymer matrix composites under mechanical/environmentalloading condition.

-       FEA Modeling: Progressive damage modeling of material in ABAQUS usingUMAT subroutine.

-       Destructiveand non-destructive testing:Shear creep, tensile, compression, flexure, and short-beam shear test, opticalimage correlation, and SEM.

-       Fabrication: Extrusion, pultrusion, compression molding, filamentwinding and Vacuum Assisted Resin Transfer Molding (VARTM).

Achievement:

Developed a multi-scale mechanismbased model to predict the stiffness and strength degradation of polymer matrixcomposites in thermo-oxidative aging environment (for more details see thepublications).

 

v ResearchAssistant, July 2005 – May 2007

Structure Lab

Indian Institute of Technology, India.

Dutiesand Responsibilities:

Involvedin development of optimal design of railway track fastening system (steelmaterial) by enhancing the fatigue life of components and interacting withother members of design and manufacturing teams, perform design documentations.

-       FEA Modeling: Fatigue and stress analysis of the steel material usingANSYS.

-       HandCalculation: Optimization of 3-D beam using theinbuilt genetic algorithm tool in MATLAB.

Achievement:

By optimization the shape of railwaytrack fastening system 54% increase in fatigue life and 22% cost reduction was observed.

 

v ResearchEngineer, July 2004 – May 2005

Structure Lab

Indian Institute of Technology, India.

 

Dutiesand Responsibilities:

Performeddesigning and modeling of Aircraft Arrester Barrier System for 40 ton aircraftsand perform design reviews, and provide design recommendations. (The purpose ofaircraft arrester barrier system is to engage a fighter aircraft to halt itsforward momentum in the event of aborted takeoff or landing over run withminimal damage to aircraft or injury to the crew within a given range ofdistance.)

-    FEA modeling: Simulation of the engagement process in LS-DYNA usingdynamic and transient analysis.

-    HandCalculation: Evaluating designs for possiblestress limitations and suggesting improvements by finding the new design parameters.Coordinating with outside vendors, helping them in the analysis and checkingtheir stress reports.

-    CostEstimation: Recommended design modifications toensure structural integrity and cost estimation.

Achievements:

-    Successfully workedfor Naval aircraft at ship deck using the deliverable code.

-    It can beused for any aircraft during emergency situation in ground operation.

 

v InternEngineer, May 2004 – July 2004
