Abstract
The mathematical structure of the Head Injury Criterion (HIC) function al is described. Necessary conditions for the extremal solution of the HIC functional are presented, along with results characterizing the c ritical points of the functional. A program written in Borland C is de veloped to construct the HIC functional, and various characteristics o f the HIC are determined from the constructed functional, including th e average HIC value, HIC variance, and higher-order HIC moments. By in vestigating the form of the HIC functional, it is possible to extract structural information by the computation of the moments of the functi onal. Sample functional plots for experimental acceleration pulses are also provided. (C) 1998 Elsevier Science Inc. All rights reserved.
