SUMMARY:
 Performed stress (mechanical loads and thermal), buckling, dynamics (transient and random vibrations), fatigue
and damage tolerance analysis of primary and secondary aircraft and spacecraft structures comprised of metallic
and composite materials using computerized methods (NASTRAN, PATRAN, ANSYS, ABAQUS (for
nonlinear analysis), NASGRO, AFGROW, CATIA , EXCEL, M/S WORD, MATHCAD) and standard hand
calculations; reviewed and signed-off installation and detail drawings; wrote stress certification reports;
support disposition on non-conformances for new and refurbished parts (MRB).
 Used miscellaneous Boeing design manuals (BDMs) and Boeing in-house software (e.g. , CSW, SA, IAS, etc.)
for tension fittings, stress analysis, plasticity, composites, fatigue and damage tolerance analysis; familiar with
accessing CATIA models to view detail layouts, to obtain section properties and to interface with PATRAN for
finite element modeling and NASTRAN analysis; familiar with the combined use of IBM RS-6000 workstation
for CATIA, unix-based software (e.g. NASTRAN/PATRAN, Boeing in-house software, etc. ) and PC-based
applications software (e.g. Microsoft Office suite).
 Used miscellaneous Lockheed Martin analysis tools and Northrop Grumman in-house software, such as IMAT,
IDAT, SLIM/VISION, etc. for pulling out loads from global FEM of aircraft; refined FEM mesh and performed
detailed stress analysis, fatigue and durability check of part and fastener attachments.
