Materials Engineering Expert Witnesses & Consultants

In the last century, advances in Materials Science have elevated almost every aspect of our lives. Consider some of the new and functional materials that make living so much safer and easier: chemicals, polymers, ceramics and alloys for use in medicine and medical implants, carbon fiber reinforced plastics for varied uses including to make stronger, lighter sports equipment, and metals and coatings for sturdier and safer construction. New Material Analysis and Engineering are responsible for novel technologies in many different fields encompassing civil, chemical, construction, nuclear, aeronautical, agricultural, mechanical, biomedical and electrical engineering. 

Materials Engineering Expert Witnesses and Consultants may be called upon for several purposes.  Their expertise includes Accident Reconstruction, Failure Analyses, Product Design, Product Development, Product Delivery, and Material Handling System to name a few.

Biomechanics Expert Witnesses & Consultants

Biomechanics are defined as the scientific study of biological and especially muscular activity – as in locomotion or exercise.  Though this field of expertise is relatively new as it pertains to litigation, it is understandable why so many attorneys are turning to biomechanical engineers to support their cases. In Smelser v. Norfolk Southern Railway
Company, 105 F.3d 299, 305 (6th Cir. 1997),  it was noted that, “Biomechanics apply the principles in mechanics to the facts of a specific accident and provide information about the forces generated in the accident, explain how the body moves in response to those forces, and thus determine what type of injuries would result from the forces generated.”

Biomechanic experts are trained in Engineering as well as Human Anatomy.  This makes them particularly useful for determining causation  in personal injury and products liability cases.  For instance, in an article entitled, Experts in Mechanisms of Injury, Biomechanics Expert, Dr. Dennis Andrews, BSOSH, MSOSH, PhD, explains that seatbelt injuries must be described to the jury in two ways: (1) the mechanisms and forces causing the injury and (2) the injuries themselves (cuts, lacerations, bruises) in detail and their locations identified.

Considering the wealth of knowledge Biomechanics Experts can bring to an injury case, it is no wonder why the demand for their services has grown so drastically over the last decade.

Steel Mill Electric Arc Furnace Accidents

Steel mill electric arc furnace manufacturers and employers must be required to properly train workers to ensure a safe working environment. The following Case Scenario is an example of how improper training can lead to egregious harm and even death.

Steel Mill Electric Arc Furnace

Case Scenario: Death On A Steel Mill Electric Arc Furnace

Expert’s Job Assignment

To assist with the case by the plaintiff widow against a third party industrial company and various contractors.

Case Synopsis

Maintenance work was being done on a three phase AC electric arcfurnace that was about 30 feet in diameter. It was shut down for some extensive repairs. There were many different crafts and contractors working on different aspects of the repairs and many of them were out of sight of others.

The deceased was welding on the support section of one of the three electrode arms that hold and carry current to the main electrodes that do the melting in the furnace. The clamping section had been removed so that he could get access to the damaged area that was to be repaired, and it was being held up about 10 feet above him by an overhead crane, by means of a chain assembly on the main crane hook. The removed clamping section was an assembly of aluminum and copper that weighed over two tons.

By means of a spurious electrical signal the control circuit for the furnace sent a signal to raise all three electrode arms. The stored energy in the hydraulic accumulators did just that: all three electrode support posts rose up to their full height. In doing so one of the other arms hit the suspended clamping section and dislodged it from the overhead crane. It fell and killed the welder below.

Expert analysis

  1. The control system for the furnace required that there be a large hydraulic accumulator for each phase electrode in order to be the source of a large volume of oil so as to move the electrodes faster that the hydraulic pumps could supply the oil. These were piped to the electrode cylinders through 4 inch diameter pipes.
