Dynamic response due to behind helmet blunt trauma measured with a human head surrogate.

A Human Head Surrogate has been developed for use in behind helmet blunt trauma experiments. This human head surrogate fills the void between Post-Mortem Human Subject testing (with biofidelity but handling restrictions) and commercial ballistic head forms (with no biofidelity but ease of use). This unique human head surrogate is based on refreshed human craniums and surrogate materials representing human head soft tissues such as the skin, dura, and brain.

Evaluation of orientation and environmental factors on the blast hazards to bomb suit wearers.

This paper discusses the use of 3-D computational fluid dynamics (CFD) software for simulation of explosive detonations against the wearer of a typical bomb suit. The focus is to demonstrate the utility of the model to assess the differential overpressure loads on the various bomb suit components protecting critical body parts. Since overpressures can vary significantly depending on the position and orientation of the wearer, simulations are performed for a range of orientations including kneeling and standing at common standoff distances.
