MATERIAL FAILURE ANALYSIS; ADHESIVE FAILURE; COMPOSITE FAILURE; METAL FAILURE. Expert's principal occupation has been in the analysis of failures of machine components, including orthopedic (surgical) implants. Materials analyzed include metals and alloys of all types, polymers, elastomers, composites, adhesives, and ceramics. He also analyzes many components, including primary structures, rotating machinery, bearings, seals, fasteners, microswitches, electrical contacts, femoral implants, plates, screws, and other hard tissue replacements. Expert has over 29 years experience consulting in the aerospace industry. He has analyzed failures for boiler and machinery insurers, electric power plant operators, paper mills and other chemical processors, manufacturers of machinery, and law firms.
MECHANICAL PROPERTIES. Expert has consulted on test programs for static mechanical properties, fatigue, stress-corrosion, corrosion-fatigue, and fracture mechanics.
EDUCATION; MATERIALS SCIENCE; MECHANICAL FATIGUE. Expert has extensive instruction experience in the mechanics of materials and material science at the undergraduate level, and has taught graduate courses in mechanical metallurgy, fracture mechanics, failure of materials and fatigue in engineering design. He has also instructed in statics, dynamics, mechanical metallurgy, mechanics of materials, and chemistry for review programs for E.I.T. and P.E. examinations.
MATERIALS TESTING. A significant portion of Expert's work has involved testing materials and machine components including metals, plastics, elastomers, and composites. He has conducted monotonic and fatigue; wear and abrasion; and stress corrosion tests. FORENSIC ENGINEERING; LEGAL TESTIMONY. Expert has prepared evidence reports and given his professional opinion on the failures of femoral stems (artificial hip implants), massie nails (support for femoral ball), truck axles, fifth wheels (semi-tractor or truck), cranes, hand and power tools, improper repairs to electrical generating equipment, aircraft propeller components, electrical switches for home-heating gas furnaces, automobile parts, and accident reconstruction. He has conducted on-site investigation of failures and holds an FAA Certification in Aircraft Accident Investigation.
ELECTRON MICROSCOPY; FRACTOGRAPHY; MACHINE COMPONENT FAILURE ANALYSIS; ORTHOPAEDIC IMPLANT DEVICE. Expert is well-versed in electron microscopy and fractography, especially as applied to the analysis of failures of machine components, structures, and orthopedic implants. He also has extensive experience in quantitative fractography in using fatigue stratums for measure crack rates and to estimate the applied stress ranges.
