The Analysis of Pressure Response in Head Injury

A new approach to generating physical and numerical models of the human head is presented and we aim to investigate whether it is possible to predict the response of the head for a particular impact scenario using these modelling techniques. Finite element (FE) and rapid prototyped (RP) models were generated from the conversion of 3D image data. Both the numerical and physical models were used to validate an approximate analytical model based on full 3D elasticity equations as developed by one of the authors. Good agreement was observed between the three modelling techniques and large transient pressure amplification at the site of impact was observed for impacts of low duration.
