Expert Details

Failure Analysis and Objective Forensic Analysis: Ballistics

ID: 721797 Iowa, USA

Request Expert

Expert has expertise in the the evaluation of metallurgical failures, including root cause analysis. He spent a sabbatical at Perkins Engineering in the UK conducting failure analysis in their materials lab and has 17 years experience conducting independent investigations in this area. He has worked both with attorneys and companies to analyze failures of all types although his experience is primarily with metals. He has been deposed numerous times for his expert opinions

Expert is a Fellow of ASM International and teaches a course on failure analysis. His training is in the use of electron microscopy for characterization and has conducted research investigations in a number of areas including the development of high strength alloys, the recovery of rare earths, phase transformations in ferrous systems, and the examination of metal systems using electron microscopy.

Expert is also known for his work in the area of forensics, having conducted investigations on the objective analysis of toolmarks for law enforcement applications. He has conducted funded research to develop objective methods for the identification of toolmarks and has examined the use of microstamping as a technology for firearm and ammunition identification. He currently is involved in an FBI funded research program to test the accuracy, repeatability, reproducibility of firearm examiners.

Has conducted failure analysis on a cast Al outboard motor engine support where a child's life was lost when the accident occurred. The case was settled out of court. In an unrelated case he again examined Al outboard engine components for a possible class action suit against the manufacturer.Examined a failed engine block used for backup power generation by a small Midwestern municipality. The case was settled out of court.Assisted in the investigation of a corrosion failure in a water system that caused considerable damage. He was responsible for the metallurgical examination of the failed material. He was deposed and provided critiques of opposing experts opinions. The case was settled out of court.Examined failed metal tubing used in a gas station delivery system. In addition to delivering his opinion he critiqued experts secured by other counsel. The case was settled out of court.Assisted a company in the analysis of failures in a heat exchange in an ethanol plant. Recommendations to the company lead to changes by the plant design / construction firm to correct the problem before a law suit was filed.
