Abstract

Explosions and blast waves can cause human injuries due to both the interaction of the blast waves with the human tissues and the generated and propelled fragments that strike the body. Several models for the prediction of these injurious effects have been reviewed in this report. They have been selected from those most widely established and more suitable for implementation in finite element codes for risk assessment in large-scale numerical simulations. The models examined have been presented according to the established three categories of primary, secondary and tertiary injury mechanisms. They are probabilistic and their probit (or logistic) functions are presented and explained. Appropriate pressure-impulse and mass-velocity diagrams are drawn for blast waves and fragment injuries, respectively. Comparisons of injury criteria predictions are made, and some merits or shortcomings of the models are indicated. A workable model of munition fragmentation is also included. Thus the report provides the means for an efficient assessment of human injury risk in case of explosion events, which can effectively contribute to refining methods of protection in security and defence.
