David M. Hallman, M.S., P.E.
Forensic Engineering Consultant
Consulting Mechanical / Materials Engineer
ASE Certified Master Automotive Technician
I am a Licensed Professional Engineer in ten states with over twenty-nine years combined experience in materials research, mechanical engineering and design, crash testing research and crash investigation and reconstruction, vehicle fire research and investigation, automotive mechanics and forensic mechanical and materials investigation. I hold degrees in mechanical engineering (BS) and materials science and engineering (MS).
I work on a wide variety of forensic mechanical and forensic metallurgical 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.
My automotive background coupled with my two degrees, extensive testing and research and continuing studies qualifies me for most aspects of crash investigation and reconstruction. Some of the cases investigated include a vehicle tie rod failure that triggered a cross over crash, multiple unintended vehicle acceleration cases and cases involving heavy truck brake failure. I have also been involved in multiple cases involving tire failure analysis. Since 2011, I have been involved with several different crash teams around the country and have been deeply involved in planning and executing instrumented vehicle crash tests.
I have testified in court and in deposition on multiple occasions. All forensic engineering investigations are performed using the Scientific Method as the basis for the inquiry. The opinions presented in each matter are based on the facts of the case.
David is a member of SAE International, the National Association of Fire Investigators (NAFI), the Accident Reconstruction Network (ARC), the National Society of Professional Engineers (NSPE), Midwest Association of Technical Accident Investigators (MATAI), Southwest Association of Technical Accident Investigators (SATAI) and the National Association of Professional Accident Reconstructionists (NAPARS).
