Product Failure Expert 462716 IA

Expertise Description

I have more than 30 years experience in the fields of Product Design and Failure Analysis with expertise in the manufacture of the subject part. I have experience with analyzing the physical stresses that arise in a product under various loading conditions, and in determining if the design is sufficient to survive such loads, and investigating product failures and accidents analysis from a fundamental engineering perspective, often applying finite element analysis. I have provided consulting experience in the energy, construction, industrial, thermal fatigue, medical, transportation, crane failures, marine, commercial, utility and residential industries. I have over 15 years expert witness experience with consultations, deposition, and courtroom testimony.

Relevant Experiences

I am a mechanical engineering consultant and expert witness with more than 34 years of professional experience. I’ve analyzed hundreds of product designs, including cranes, utility booms, derrick booms, cableway towers, oil rigs, man lifts, industrial forklifts, robots, motorcycles, military vehicles, commercial trucks, aircraft and the International Space Station. I have served as an expert witness across many industries, including giving depositions and court testimony. I analyze the product design and the manufacture of the subject part, and determine what caused the failure. Typically, the product’s stress distribution is compared to overload or fatigue failure criteria. Often, industry standards or a comparison to similar designs will help pinpoint the problem. I have provided litigation consulting in the energy, construction, industrial, medical, transportation, marine, commercial, utility and residential industries. I have served as an expert witness, given deposition testimony, testified in court and arbitration hearings, and supplied legal team technical support.

I have worked numerous boom truck and man lift cases and have also provided engineering consulting services on the design of these types of products.
