  • Phoenix

Mr. Bare specializes in the analysis and reconstruction of motor vehicle crashes involving passenger cars, light and heavy trucks, and sport utility vehicles. He has over 25 years of experience in the reconstruction of complex accident situations including high-speed collisions, pole/guard rail impacts, and post-collision fuel-fed fires. In the process of his analysis, he has conducted numerous physical demonstrations including high and low-speed full-scale crash tests, vehicle component and restraint system testing, and handling demonstrations. He has particular expertise in the investigation of vehicle rollover crashes including assessments of vehicle handling, tire/component failure, rollover dynamics, and rollover stability. Mr. Bare further has an in-depth background in the analysis of computer programs and simulations used for vehicle dynamics, rollover simulation, and the reconstruction of crashes.

Mr. Bare is experienced in the evaluation and use of event data recorder (EDR) data found in airbag control modules (ACM) and heavy truck electronic control modules (ECM). He has extensive background in the testing and evaluation of the accuracy and timing of the data recorded by EDRs. Other research activities of Mr. Bare include evaluations of vehicle and occupant response during heavy truck sideswipe collisions, roof crush during rollover crashes, energy dissipation during high-speed collisions, and the assessment of the energy associated with utility pole fracture.
