The Head Injury Criterion (HIC) functional

摘要

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 program written in Borland C is developed to construct the HIC functional, and various characteristics of the HIC are determined from the constructed functional, including the average HIC value, HIC variance, and higher-order HIC moments. By investigating the form of the HIC functional, it is possible to extract structural information by the computation of the moments of the functional. Sample functional plots for experimental acceleration pulses are also provided.
