Impact Testing and Human Response

Research in injury biomechanics at UMTRI uses laboratory experiments with human surrogates to study the mechanical response of the human body to dynamic loading and to determine the mechanisms of, and tolerances to, different body types of injury. The results are used to develop new injury criteria and injury assessment tools that are used to evaluate the effectiveness of restraint technologies and design countermeasures. Injury assessment tools include improved anthropomorphic test devices (crash dummies), test procedures, and computer models that simulate occupant kinematics and dynamics.
