Injury models should use the PWT to delineate the area of damage to tissues from penetrating ballistic projectiles. The PWT, or its individual components, will require quantification in terms of the amount of damage produced by different projectiles penetrating these tissues. There is a lack of information qualifying the injurious effect of the temporary cavity, particularly in relation to that caused by explosive fragments, and future models should introduce modularity to potentially enable incorporation of these mechanisms at a later date were they found to be significant.

The material models used to define the properties of each element within the model will be sequentially replaced by ones specific to each individual tissue within an anatomical structure. However, the cumulative effect of so many additional variables will necessitate experimental validation against both animal models and post-mortem human subjects to improve the credibility of any predictions made by the model. We believe this approach will in the future have the potential to enable objective comparisons between the mitigative effects of different body armour systems to be made with resultant time and financial savings.
