“If it bent or broke causing loss, injury or death, I can help explain the failure.”™

Steve Roensch is a mechanical engineering consultant with 42 years of professional experience. He has analyzed hundreds of product designs and has served as an expert witness in 77 cases, testifying 23 times at deposition, court or arbitration.

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 has provided litigation consulting in the energy, construction, industrial, medical, transportation, marine, commercial, utility and residential industries. He has served as an expert witness, given deposition testimony, testified in court and arbitration hearings, and supplied legal team technical support. He has served as an expert on patent cases involving engineering product design.

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.
