 Extremely efficient in performing stress analysis by conventional hand calculations and energy principles

 3+ years of experience in determining fatigue life and damage of structural components through hand calculations and FEA programs

 Know how of fracture mechanics principles and experience in building damage tolerant designs based on fracture parameters chosen

 Competent in performing ply-by-ply failure analysis of composite structures and experience in manufacturing composites using wet and dry hand lay up techniques

 Excellent programming skills in FORTRAN, MATLAB, C and highly skilled in Microsoft office

 Highly organized, dedicated and shown ability to perform effectively under pressure in a team or as an individual

SPECIAL PROJECTS

At University of Kansas, Lawrence, Kansas

 Modeled and simulated a 16 layer composite laminate using MSC Patran-Nastran software to analyze ply-by-ply stress/strain failures at different temperature and moisture gradients

 Structural Design Lead for UAV Mars flyer. Design included light weight wing and fuselage structure, tail boom attachment and parachute release mechanism at 10,000 feet altitude

 Flight Test Engineer for Cessna 172M aircraft

 Masters Final Project: “Fatigue Fuse Indicator Design” for indicating and monitoring damage of a structure subjected to dynamic loads throughout its life. The layered fatigue fuse concept was a visual investigation process for the underneath structure’s damage life

At Embry-Riddle Aeronautical University, Daytona Beach, Florida

 Residual strength analysis on S2 glass and carbon fiber prepreg laminated coupons upon Barely Visible Impact Damage (BVID) using C-Scan Ultrasonic Imaging System

 Class project on stress analysis of aircraft plates and shells using NEi Nastran

At Institute of Aeronautical Engineering, Hyderabad, India

 Trajectory reconstruction of a flight vehicle’s path using Matlab and Simulink

WORK EXPERIENCE

Application Engineer, NEi Nastran Software HQ, Westiminster, CA, July 2008-Present

 Assisted in enhancement, testing, maintenance and support of NEi Nastran engineering analysis tools including software development responsibility

 Supported NEi Nastran analysis areas includes: Linear static, Buckling, Normal modes analysis, Transient response analysis, Shock and response spectrum, Frequency response, Random response, Pre-stress, Vibration fatigue and Non-linear analysis

 Supported customers in gathering requirements for hardware and software related problems and provided a strategic planning of NEi tool usage

 Assisted in Fatigue and Vibration Fatigue modules enhancement in NEi Nastran. Built fatigue verification models in FEMAP, analyzed in NEi solver and compared results with values estimated through analytical means. NEi Fatigue analyses included S-N (stress life/or Total life) and E-N (Strain life/or Initiation life) approaches

 Assisted in developing an interface between available Fracture mechanics (Crack growth analysis/or Propagation life) code and NEi Nastran solver for 2D and 3D cracks using Visual Studio Fortran 2008

 Provided technical support to the sales team by demonstrating the feature and benefits of NEi Fatigue/Fracture products in terms of technical aspects to ensure product growth and achieve required goals

Intern, NEi Nastran Corporation, Westiminster, CA, March 2008-July 2008

 Assisted technical and development team by testing FEA models, reporting errors and help them corrected

 Documented tutorials for advanced and basic FEA users

 Surgical Hip Stem Implant Design Project: The tapered medical stem implant for human hip replacement was re-designed for optimal performance using Solid Works 2008. The medical implant consisted of: Stem, Neck, Head, Cup or Shell and Silicon tubing. The medical implant project was divided into 3 phases:

Phase1 included re-design of existing medical implant geometry for optimal usage

 Femoral Stem geometry was re-designed for minimal bone removal from the patient. Stem was made inline with the long axis of the femur to provide desired amount of leg length

 Neck geometry was angled at approximately 50o from the femoral axis to provide proper component position, joint stability, improved range-of-motion for Head-Cup movement and leg length

 Head and Cup size was designed to be flexible depending on individual hip size obtained from radiograph followed by determining intended center of rotation for bearing surfaces

 Silicon tubing was designed to be placed over Head-Cup bearing surface integration for protecting metal filings from falling into the bone and getting hazardous

Phase 2 included assisting product manager in patenting proposed medical implant design

Phase 3 included assisting senior technical manager in analyzing the behavior using FEA

Research Assistant, University of Kansas, Lawrence, KS, August 2006-March 2008

 Conducted fatigue analysis on steel coupons in developing fatigue fuse indicator

 Was responsible for fabricating carbon fiber mirror blanks for space telescopes

Intern, Center for Composite Materials, Newark, DE, May 2007-August 2007

 Was responsible for conducting “Finite Element modeling and simulation of rain drop impact” on Polymethylmethacrylate (PMMA) plate using LS-DYNA

 Rain drop was modeled using meshless Smooth Particle Hydrodynamics (SPH) technique and PMMA using solid elements. Different numbers of rain drop particles were used to make a convergence study and reproduce in detail the dynamics of impact event and subsequent penetration inside the PMMA target

COMPUTER SKILLS

 C, C++, FORTRAN 77, MATLAB, AUTOCAD, CATIA V-5, MSC PATRAN, MSC/NX/NEi NASTRAN, NEi FUSION/WORKS, FEMAP, LS-DYNA, SOLIDWORKS 2008, VISUAL STUDIO 2008, MS OFFICE, OS-98, XP, Vista
