The mathematical structure of the Head Injury Criterion (HIC) functional is described. Necessary conditions for the extremal solution of the HIC functional are presented, along with results characterizing the critical points of the functional. A. Head Injury Criterion and the ATB By Brian G. McHenry McHenry Software, Inc. Introduction Injuries to the head are responsible for 50, deaths and nearly one million hospitalizations per year in the United States. Motor vehicle crashes are responsible for nearly half of these head injuries1. Head injury continues to be a leading cause of. The Head Injury Criterion (HIC) is a measure of the likelihood of head injury arising from an impact. The HIC can be used to assess safety related to vehicles, personal protective gear, and sport equipment. Normally the variable is derived from the measurements of an accelerometer mounted at the center of mass of a crash test dummy’s head, when the dummy is exposed to crash forces.

Head Injury Criterion and the ATB By Brian G. McHenry McHenry Software, Inc. Introduction Injuries to the head are responsible for 50, deaths and nearly one million hospitalizations per year in the United States. Motor vehicle crashes are responsible for nearly half of these head injuries1. Head injury continues to be a leading cause of. The quantity known as the Head Injury Criterion (HIC) is in actuality two things in one: a number and a criterion based on that number. Gina Rablau 2 The HIC number is calculated starting from the short-lived but extremely large time- Microsoft Word - Crash Safety Test. The mathematical structure of the Head Injury Criterion (HIC) functional is described. Necessary conditions for the extremal solution of the HIC functional are presented, along with results characterizing the critical points of the functional. A. Severity Index and the Head Injury Criterion The first model used in practice was the Severity Index SI. The value of the deceleration was weighted by a power n, the value of which depended on the part of the body according to empirical experience. For the head, n = was chosen. The SI was defined in mathematical form by SI= a(t)"dt, Jo. The Head Injury Criterion (HIC) is a measure of the likelihood of head injury arising from an impact. The HIC can be used to assess safety related to vehicles, personal protective gear, and sport equipment. Normally the variable is derived from the measurements of an accelerometer mounted at the center of mass of a crash test dummy’s head, when the dummy is exposed to crash forces. In humans, the brain injury criteria are indicators to evaluate the extent of an injury.
