Two anthropomorphic test dummy (ATD) heads are evaluated for biodynamic fidelity in a combined experimental and analytical study. In the experimental investigation, a Part 572 head, a Hybrid III head, and a series of cadaver heads were subjected to the same impacts. Limitations on the use of ATD head accelerations as human injury predictors are examined. Intracranial pressures are calculated from the head accelerations using a finite element brain model.
