|Developed and validated the cohesive zone methodology for
modeling fracture. Focused on interfacial and bulk fracture in brittle,
ductile, and rate-dependent material systems subjected to static and dynamic
loading environments. Collaborating with experimentalists to model
specimen geometries and determine the applicability of numerical methods
for modeling fracture in full-scale components.
|Lead analyst for a resistance welding effort. Developing a validated
3-D electrical-thermal-mechanical predictive capability to accurately simulate
temperatures, distortion, and residual stresses due to the gas transfer
system (GTS) resistance welding processes.
|Thesis work focused on titanium metal-matrix composites. Predicted
the effects of environmental degradation, material inelasticity, and evolving
damage on specimen life. While at Sikorsky Aircraft, I fabricated
composite test specimens, constructed dynamic wind tunnel models, and built
UAV flight vehicles.
|Employed various methods for the justification of ultimate, fatigue,
and damage tolerance requirements for Boeing Commercial aircraft.
Discovered the advantages and limitations of semi-monocoque metal construction
through examination of full-scale testing, production processes, maintenance
practices, and service history.
