EXPERIENCE:

Senior Stress Engineer

Stress Engineering, C&D Zodiac, La Palma, CA, USA                  Sept 07 – Present

• Led a team of direct report stress engineers
• Led all stress engineering activities of EMBRAER commercial aircraft interiors: ERJ 135/145/170/190 family of commercial aircraft (except seats), Airbus/Boeing Regional Airlines STC programs and some specialty programs
• Managed engineering budget, time and schedule of the stress department
• Determined and advised the designers on certification requirements for new configurations and reconfigurations per FAA (14 CFR Part 25) requirements, assigned work load to the team, checked and approved FEA models, calculations and stress reports
• Signed off drawings and dispositioned QC non conformities in parts as a member of the MRB
• Coordinated with interior design leads and OEM stress engineering teams, provided analysis support and feedback for new designs
• Found solutions to various internal and external customer stress issues, supported design change requests. Example of a tough project was passing an under bin unit without top attachments at 9500lb load, other unique projects include nonlinear transient analysis efforts of a dynamic seat test using Nastran
• Maintained team morale, set performance goals and standards, conducted employee reviews and actively sought ways to improve efficiency and substantiation techniques
• Interacted constantly with top program management and OEM stress engineering groups on stress certification issues

Stress Engineer

Stress Engineering, C&D Zodiac, Huntington Beach, CA, USA               May 06 – Aug 07

• Performed stress analysis of aircraft interior systems such as galleys, bulkheads, bins, class dividers etc. mostly composed of composite honeycomb materials using Nastran and FEMAP for TC projects such as Airbus, Boeing and Bombardier aircraft as well regional airlines STC projects
• Performed FEA of the interior units & hand calculations of detail parts. Suggested design changes to improve structural integrity to satisfy customer requirements and FAA or relevant regulatory authority requirements for structural substantiation during static testing
• Generated reports such as interface loads, stress analysis, fitting analysis, static test plans, & static test results among others
• Planned and conducted static tests of the units in the test facility for certification and approval for production and installation on aircraft, validated analysis results using test results

Applications Engineer

Technical Support Team, NORAN Engineering Inc., Westminster, CA, USA             May 05 – April 06

• Provided telephone and email technical support to customers of the company’s FEA products as an applications/technical support engineer
• Demonstrated company’s products to prospective customers as part of pre-sales support for the sales team
• Conducted training for linear and nonlinear static, dynamic analysis using NEiNastran and FEMAP courses
• Attended trade shows and set up booths at user conferences to demonstrate and promote company’s FEA products
• Led QA, testing, bug reporting, regression testing, online user’s guide documentation, tutorials, and enhancements of new and innovative products such as NEiWorks, a Solid Works embedded NASTRAN pre/post processor
• Applied knowledge of products towards technical writing such as white papers, online tutorials, knowledge base contributions, magazine publications, and web forum support

Structural Analyst

      Analysis Team,Sturman Industries Inc., Woodland Park, CO, USA              Oct 01 – April 05

• Structural analysis and modeling for all the product groups of the company including IFE(intensified fuel injectors) and HVA (hydraulic valve actuation) groups
• Conducted an in house seminar showing ‘Design for FEA’ concepts to the designers, such as sliver geometry that could affect modeling
• Led the process of upgrading and maintaining the company’s FEA capabilities
• Assisted design and development teams in injector, valve, pump, actuator and other systems and subsystem component design with FEA support from concept to prototype development and testing
• Documented and presented analysis results to both internal and external customers in support of projects as well as business management teams
