Stress Engineer and Finite Element Specialist

TECHNICAL SKILLS:

Extensive experience in Linear and Non-Linear Structural Stress and

Vibration Analysis using classical hand calculations and Finite Element

Methods. Extensive experience in FEM Software Development and Testing.

Languages C, FORTRAN, C++, Pearl, PCL, VBA

Environments UNIX, Microsoft Office, Microsoft Studio

EXPERIENCE:

STRUCTURAL ANALYSIS:

. Performed structural analysis on metallic and composite parts in FLE

(Fixed Leading Edge) and MLE (Movable Leading Edge) of Boeing 787 using

PATRAN, NASTRAN and Hand Calculations. Performed ECAP and GK-Joint

Analysis.

. Performed stress, quasi-static, modal, shock, frequency response, random

vibration, structural/thermal, fatigue and durability analyses on

aircraft wings, slats, fuselage and radar electronic boxes. Obtained

interface bending moments and shear loads using FEM methods (PATRAN &

NASTRAN) and hand calculation for safety margins in frames, shear ties,

stringers and skins. Used Excel spreadsheets and VBA to automate load

calculations for buckling and crippling analyses.

. Performed stress, vibration, crash, and thermal analyses on automotive

structures and components including Shock Towers, A pillar, White Body,

Fuel Tanks, Composite Hoods, Power Trains, Pistons, Connecting Rods,

Crankshafts, etc. at Ford and GM.

. Studied the effects of inherent process variables during the simultaneous

stretching and bending of open and closed section tubes in roll forming

using ABAQUS and PATRAN. Developed a procedure using FORTRAN to automate

analysis that bridged the gap between ABAQUS and PATRAN at GM Research

Center.

STRUCTURAL ANALYSIS SOFTWARE:

. Architected, designed, developed and implemented a complete pre and post

processor in MSC/PATRAN for ABAQUS that included the entire development

cycle of coding, testing and creation of regression tests. Led a team of

10 engineers in designing and developing a generic infrastructure in

MSC/PATRAN for 3D contact which was used for ABAQUS, NASTRAN, ANSYS and

MARC Interfaces. Spearheaded a project to add Parametric Study and

Optimization into NASTRAN Interface of PATRAN. Collaborated with the

NASTRAN development team to add new nonlinear stress analysis

capabilities into NASTRAN Interface.

. Dealt with Super Elements including persistent database entity, database

API, GUI design and QA requrements with a core design generic enough to

be used with all finite element solvers.

WORK HISTORY:

l-3Com, Greenville, TX Jan, 2013 - Present

Contract Stress Engineer

Checking structural integrity of Bombardier's Q400 aircraft modification

for special missions using FEM tools and classical hand calculations.

Developed tools using VBA, PCL and C++ to automate the structural analysis

process.

Boeing, Everett, WA May, 2011 - Jan,

2013

Contract Stress Engineer

Worked on 787-9 structural loads generation from the aero loads for input

into the FEM models of the Fixed Leading Edge (FLE) and the Moveable

Leading Edge (MLE). Generated Interface Loads from the FEM Analysis to be

used as input to the other structures of the airplane. Generated Internal

Loads from the FEM Analysis to assess the structural integrity of metallic

and composite parts using Boeing Design Methods and hand calculations.

Spirit Aero, Tulsa, OK May, 2006 - May, 2011

Contract Stress Engineer

Worked on 787-8 and 787-9 structural integrity for FLE(Fixed Leading Edge)

and MLE (Movable Leading Edge) Skins(Carbon Fiber Laminates),

Ribs(Aluminum) and Fasteners(Titanium) using PATRAN and NASTRAN. Used Catia

and Enovia to access parts and components and data. Used ECAP, GK-Joint,

CSW tools and Boeing Design Methods to do strength checks.

L3-Communications, Greenville, TX April, 2005 - March,

2006

Contract Stress Engineer

Performed margins checks on the modified structure of a DC-10. Used PATRAN

to create FEM model of the structure and NASTRAN to extract the interface

loads at the critical locations. Used classical Hand calculations for

buckling and crippling of frames, shear ties, stringers and skins using

bending moments and shear loads at the interfaces. Developed a procedure in

Excel using Macros and VBA subroutines to automate the calculations of

loads, stresses, buckling/crippling allowables and safety margins.

Lockheed Martin, Ft Worth, TX February, 2004 -

March, 2005

Contract Stress Engineer

Worked on the JSF program with designers to validate structural integrity
