Additional Information

David Hallman is a Licensed Professional Engineer in six states and has over twenty five years combined experience in materials research, mechanical engineering and design, crash testing research and crash investigation / reconstruction, vehicle fire research and investigation, automotive mechanics and forensic mechanical and materials investigation . He holds degrees in mechanical engineering and materials science. His extensive hands-on experience as a mechanic coupled with his two degrees makes him ideally suited for all types of failure investigations. These investigations have included but are not limited to an elevator failure involving materials and design issues, a personal injury involving a paper shredder, multiple cases involving farm equipment and personal injuries, machine guarding cases, chair collapse cases, bolted joint failures, patient lifter failures, vehicle hand control issues, and tipped telehandler and boom crane cases. David's automotive background coupled with his two degrees makes him ideally suited for all aspects of crash investigation and reconstruction. Some of the cases investigated include a vehicle tie rod failure that triggered a cross over crash, several unintended vehicle acceleration cases and cases involving heavy truck brake failure. David has also been involved in multiple cases involving tire failure analysis. Since 2011, David has been involved with several different crash teams around the country and has been deeply involved in planning and executing instrumented vehicle crash tests.
