Air Blast Exposure and Injury

Air Blast Exposure and Injury


Is shoulder-fired-weapons training causing serious unintended effects on trainees? Currently, there is limited understanding of blast exposure levels from training. Experiments provide some information on blast overpressure.


ARA created computational models to simulate blast exposure on operators of shoulder-fired weapons using the SHAMRC high-fidelity multi-physics code. The model was validated with experimental pressure data from a number of training events. The simulations provide blast exposure levels over the entire body.


The military now has a much better understanding of blast exposure levels on operators. In addition, information from simulations can be used to study medical outcomes from blast exposure, not only in training but in other scenarios.
