Logo "If it bent or broke causing loss, injury or death, I can help explain the failure."Â â„¢

Steve has a robust background in engineering mechanics, physics and mathematics, and 42 years of professional experience analyzing product designs and failures. His workload is a combination of consulting on product designs and serving as an expert on injury, death, loss and patent cases. He has worked on a wide array of product designs, from utility task vehicles (UTV, SSV, SxS, ROV, ROPS) and all terrain vehicles (ATV) to farm equipment, oilfield equipment to robots, military vehicles to the International Space Station (ISS). Steve holds an M.S. in Engineering Mechanics and a B.S. in Applied Mathematics, Engineering and Physics with Honors.

Steve has served as an expert witness on 77 cases and has testified 23 times. He has taught engineering classes at the University of Wisconsin-Madison, Marquette University, IBM Research & Development, and at client locations. In addition to a very strong theoretical background, he is a hands-on engineer, and has performed maintenance and repairs on his own SUVs, boats and aircraft.

Steve can be of assistance when a product fails in a physical manner, such as bending or fracturing, and the failure results in loss, injury or death. He will 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.

Steve specializes in 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. He investigates product failures and accidents from a fundamental engineering perspective, often applying finite element analysis. He documents his efforts thoroughly from the start, for concise presentation to the legal team, other experts and the jury.

Complex engineering principles are explained using everyday concepts that everyone can understand. Color stress plots and animations are used whenever possible to convey complicated engineering results in an easy to understand visual format.
