My career of over 20 years in the field of mechanical engineering has specialized in finite element analysis, strain gage testing, mechanical design, and fatigue design. I have additional knowledge in linear and non-linear studies, contact analysis, bolted joints, welds, fatigue, modal analysis, and both steady state and transient thermal studies, including thermal-structural interactions.
I have more than 15 years experience in mechanical engineering with a focus on design and failure analysis (failure of bolts and bolted connections to dynamic stability of scissors lifts and excavators to mechanical failure of hydraulic system components to mechanical behavior of industrial equipment), engineering research (detailed studies of the flange stress response, creep behavior of longitudinally welded pipes at high temperature, design of structural supports for a cryogenic superconducting MRI machine, design review of medical implants, dynamic analysis of multistory manufacturing facilities, and frequency analysis of silicon wafer fabrication components), Finite Element Analysis (simple two dimensional linear elastic analysis of pressure vessels to complete three dimensional nonlinear analysis of a bolted engine connecting rod and full contact dynamic analyses of crane clutch components), Accident Reconstruction and Crash worthiness, and Mechanical Testing. I have extensive experience in industrial equipment injuries and failures, including fans and other rotating machinery. I have over 10 years expert witness experience with consultations, deposition, and courtroom testimony.
I have more than 15 years experience in Fastener Engineering. I focus on process design, product and process reliability, and product applications. My expertise includes fastener manufacturing (raw materials; fastener metallurgy, including raw materials, forming, ultrahigh strength fasteners, and heat treatment; quality assurance; manufacturing engineering support; automated inspection methodology; lean manufacturing and cost reduction; and coatings, corrosion cracking, including electroplating, galvanizing, phosphating, and emulsions); applications engineering (joint analysis in automotive, structural, machinery, fluid storage & pipeline, pressure vessels and other applications; fastener selection and design; fastening technology and methodology); stress and vibration; and laboratory and testing (failure analysis; applications testing; fastener laboratory design). I have over 5 years expert witness.
