PROFESSIONAL EXPERIENCE

Graduate Research Assistant Mar ‘15 – Present

National Institute for Aviation Research (NIAR),

Computational Mechanics Laboratory, Wichita, KS

o FEA modeling of full aircraft structural components like wing, fuselage etc. using Hypermsesh

o Composite modeling of aircraft radome using Hypermesh o Post-processing and documentation of numerical analysis results (stress analysis, load path analysis, energy plots, etc.) using Hyperworks and MS-Tools Relevant Projects at NIAR

FEA Modeling of a Full Aircraft Model

o Generated 2D mesh of wings and fuselage using Hypermesh for FEA modeling of Boeing 737 aircraft

o Performed assembly tasks such as intersection and penetrations o Documented all the quality parameters of the modeled parts for efficient FEA modeling

FEA Modeling of an Aircraft Seat

o Generated 2D and 3D FEA models per client requirements from the geometry provided by them using Hypermesh

o Followed rules and regulations prescribed in AC 20-146 for computer modeling techniques o Post processed and documented the results as a technical report to the clients

FEA Modeling of an Aircraft Radome

o Generated a finite element composite modeling of certain radome structural parts from the geometry provided by the customer using Hypermesh

o Evaluated the structural integrity of primary parts and loads on fasteners during impact o Post-processed the results and authored technical reports

Frontal And Rear Impact for a Hybrid-III 50th percentile ATD o Developed a seat model using MADYMO with a dummy positioned on it along with a seat belt

o Applied an acceleration pulse to the dummy in –Gx for rear impact and +Gx for frontal impact while the seat was fixed

o Calculated the neck loads, neck moments and neck injury values from the analysis and compared against the FMVSS 208 standards

GRADUATE THESIS WORK

Title: Design and Analysis of a Composite Beam for Side-Impact Protection of Occupants in a Sedan

Developed a design to replace the current side impact beam in a Ford Taurus car

Used a composite material instead of steel to reduce the total weight of the car without sacrificing the safety of passenger

Determined intrusion and energy absorbing capacity of the beam in accordance with the basic principles of crashworthiness

Determined effectiveness of the beam by testing the finite element model of Ford Taurus car according to FMVSS 214, IIHS and side pole test

Generated 3D surface plots using the “Kriging Model” in MATLAB CONFERENCES

Presented a paper on “Design and Analysis of KNUCKLE for All-Terrain vehicle” at Amrita College of Engineering, Coimbatore, India in October 2009

Presented a paper on “Air Charging System in Diesel Locomotives” at MJCET, Hyderabad, India in August 2009
