abstract

This paper presents a study to provide guidance on the use of body-worn blast overpressure sensors to predict the risk of blast induced closed head trauma and lung injury. Data collected from blast sensor systems, when used in combination with modeling and simulation, can recreate the full loading on the warfighter [1]. Using field blast data from a 4 sensor time-synched blast system, the incident blast wave and direction was reconstructed and used as input to computational fluid dynamic (CFD) simulations of blast impacting an outfitted warfighter. Pressures around the head and underneath the helmet were found to be in agreement with experimental data. The peak resultant head velocity, which is shown to be a correlate of concussion, was also found to correlate with incident impulse over a wide range of blast conditions. Lung injury was assessed for every blast condition, revealing that some blast directions and intensities more readily engage multiple modes of injury. With the accurate reconstruction of the true blast loading to a warfighter, damage correlates obtained from biomechanical modeling analysis can be calculated for correlation with medical outcomes.
