Consultant, 2005 – present. Manager of LLC consulting firm specializing in fatigue and fracture of materials, fatigue lifetime predictive techniques, materials compatibility/selection, design optimization, cast materials, failure analysis, etc.
Rockwell International Science Center, Thousand Oaks, CA
Sr. Research Scientist, 1977 to 2002. Performed basic and applied research for a variety of programs with funding from Corporate, Intra-company and Government sources. Worked closely with Rocketdyne Div. (presently P&WA Corp.) and Automotive Div. (presently Arvin-Meritor) as program manager and principle investigator for such programs as: strain-based cumulative damage techniques for advanced propulsion systems, developed test methodologies for cryogenic (LHe and LN2) and ultra high temperature (3000oC) research of advanced material systems, anticlastic behavior of Al-Li alloys, shear strain-based damage analyses for titanium alloys, permeability of epoxy composite and CMC’s to gaseous hydrogen at high pressures (5000 psi), high frequency (300 Hz) fatigue of Al-Li, gamma TiAl and P&WA 1484, narrow-band spectrum fatigue of vertical axis wind turbine blades, ion implantations for improved bearing corrosion/fatigue resistance, fatigue enhancement of gears for heavy vehicles using high carbon induction hardened bainitic microstructures, direct metal fabrication/rapid prototyping of engineering structures, developed test methodology/design program for fatigue/corrosion of steel cables in window regulators, modification of case microstructures with ultrasonic agitation, failure analysis of C-17 landing gear, failure analysis of “Rocketcar” at Disneyland, failure analysis of C-130 ammunition storage/handling system, failure analysis of hydrogen vent LVDT for Space Shuttle Discovery, litigation team member – NYCTA (New York City Transit Authority) lawsuit on subway truck failures – after 25 years.
Manager, Physical Metallurgy Department, 5 years. 14 professional staff members with diverse backgrounds in alloy development, process metallurgy, diffusion bonding, superplasticity, mechanics of materials, rapid prototyping, etc. Six Corporate Short Courses on Fatigue of Materials.
