I have over 13 years of experiences in the stress/fatigue/damage tolerance analysis of metallic/composite structures using classical and finite-element methods. I supported design engineering in various phases from design concepts to final drawing releases and resolved MRB issues. I wrote final stress analysis reports to substantiate structural integrity. I have used MSC Nastran/Patran, Femap, I-DEAS, Mathcad, Matlab, CATIA V5, MS Office, IAS, CSW, and REDARS.


Astro Aerospace, Carpinteria, California – January 2017 to December 2017, Stress Engineer

Advised designers on ways to modify part designs to meet program strength requirements.

Designers met the critical design review milestones because of my stress analysis support.

Improved the formatting of stress reports.

Generated free body diagrams when necessary for part analyses.

Analyzed parts of a deployable structure for a satellite.

Mechanical and thermal hand and finite element analyses using Solidworks Simulation of metal parts.

Hand analyses of composite tubes and corresponding bond joints.

Boeing Co., Defense and Space, Tukwila, Washington – June 2015 to January 2016, Stress Engineer

Contributed to a white paper describing how to perform acoustic and dynamic analyses.

Supported an associate technical fellow in acoustic and dynamic analyses of various structures running solution 103 and 111 in Nastran/Patran. Matlab scripts used to post process the solution 111 analyses.

Durability and damage tolerance analyses using 5505 in CSW on an F-22 fitting.

Lug analysis of an F-22 frame.

UTC Aerospace Systems, Chula Vista, California – June 2012 to June 2015, Stress Engineer

Met analysis deadlines in a fast paced and high pressure environment.

MRB (Material Review Board) Stress Engineer on the thrust reverser of the Boeing 787 and A350 airplanes.

Evaluated, dispositioned and wrote stress analysis reports for non-conforming parts and assemblies.

Composite analyses using Nastran/Patran, BJSFM, LIPSAS, and hand calculations on the bond, acoustic, and external panels.

Buckling, crippling, bending, fatigue, and joint analyses on aluminum hardware of the thrust reverser such as hinge beam, latch beam and v-blade.

Boeing Co., Commercial Airplanes, Everett, Washington – January 2006 to June 2012, Stress Engineer

Analyzed primary and secondary structures in the wing and empennage of the 737 in the factory and fleet support group.

Stress analysis support for an optimization study of the wingbox for the 777-X.

Determined stress concentration factors for the composite upper wing skin of the 777-X using Nastran/Patran.

Developed an Excel spreadsheet to expedite the 777-X integral stringer design by calculating geometric properties of the cross-sections.

Stress analysis of the elevator and rudder static tests for the P8-A Poseidon.

Cross-section crippling analysis of the fixed leading edge auxiliary track support ribs of the P8-A Poseidon.

Fatigue analysis of the wing spoiler lugs of the P8-A Poseidon.

Used Nastran to reduce bolt bending by calculating elasticity of bolted joints in the elevator of the P8-A Poseidon.

Wrote formal stress notes for various parts of the wing structure of the P8-A Poseidon.

Panel buckling and bolt shear analysis of slat 1 of the 737-900ER.

Shear analysis of the main pin and tension analysis of the support bolts of the 747-8 flap track 4 aft attachment and determined the vertical travel of the joint and the force in the springs.

Electroimpact, Inc., Mukilteo, Washington – June 2005 to October 2005, Mechanical Engineer

Created an optimal design of an offset ram for expected loading conditions using Ansys.

Designed a test setup for an offset ram that swages bolts.

Part of design team for a machine that inserts and swages bolts for Kawasaki Heavy Industries.

Partly responsible for the design of the way cover, bellows, corresponding adapter plates, cable-track for wire and hoses, and the brackets for mounting the cable-track and hoses of the machine for Kawasaki Heavy Industries.

China Lake Naval Air Warfare Center, China Lake, California – July 2002 to August 2004, Mechanical Engineer

Structural analyses, thermal analyses, design and testing of hardware for the Department of Defense.

Designed a deployment mechanism for a sensor of a system that is deployed from an unmanned aerial vehicle that performed successfully during its first field test.

Structural analysis of a beam supporting ATFLIR pods that are lifted by crane into a test area.

Thermal analyses of various rocket nozzle designs using Pro-Mechanica for the Joint Common Missile.

Developed a grain design for a rocket used for tests run on a supersonic track.

Participated in laboratory and cockpit tests to determine the functional status of the digital communication system in the F/A 18 E/F aircraft.

Performed thermal test of the prospective lens for the seeker of the SPIKE missile.

Verified image quality, measured dimensional changes, and wrote the report of the thermal test of the SPIKE missile.

Designed and created drawings of the parts and assemblies for the seeker of the SPIKE missile using PRO-E.

For the KTM camera tracking mount, I designed two doors for environmental protection of connectors, a tiltmeter enclosure, and a rack to hold replacement azimuth and elevation control chasses using SolidEdge.

Fabricated the prototypes for the KTM camera tracking mount myself in the Instrumentation Operations Building machine shop.

Stress analysis of the camera mount for the AV-8B aircraft using I-DEAS.

Thermal analysis of the Rolling Airframe Missile rocket nozzle using I-DEAS.
