The Effect of Ambient Pressure on Blast Reflected Impulse and Overpressure
Experimental Techniques, 2017Reflected blast pressure and impulse for bare 226.8 g spherical C-4 charges under various atmospheric pressure conditions were studied both experimentally and numerically. Blast pressure measurements were conducted using an array of high resonant frequency tourmaline-based piezoelectric pressure transducers to record normally reflected blast pressure ...

Membrane characteristics for biological blast overpressure testing using blast simulators.
Biomedical sciences instrumentation, 2016Blast simulators often use passive-rupture membranes to generate shock waves similar to free-field blasts. The purpose of this study was to compare rupture patterns and pressure traces of three distinct membrane materials for biological and biomechanical blast studies.

Effects of Filtering on Experimental Blast Overpressure Measurements.
Biomedical sciences instrumentation, 2016When access to live-fire test facilities is limited, experimental studies of blast-related injuries necessitate the use of a shock tube or Advanced Blast Simulator (ABS) to mimic free-field blast overpressure. However, modeling blast overpressure in a laboratory setting potentially introduces experimental artifacts in measured responses.

Effects of blast overpressure on the ear: case reports.
Journal of the American Academy of Audiology, 1997The case histories of five patients who experienced blast overpressure in excess of 200-dB peak pressure level are presented. Despite the significance of the sound pressure levels received in a military training accident and the severe injuries that resulted from the blast, these individuals experienced substantial improvement of hearing 1 year later ...

Brain Vulnerability to Repeated Blast Overpressure and Polytrauma
2009Abstract : It is likely that the mild TBI and cognitive impairments observed among many of the troops returning from OIF and OEF result from repeated exposures to blast overpressure. Although the clinical symptoms of concussion are typically transient, there is both a cumulative risk for persistent damage due to repeated concussions, and a post ...

Evaluation of Test Methods on Personal Protective Equipment for Blast Overpressure
Personal Armour Systems Symposium (PASS 2020)In recent conflicts, a major source of injury for military personnel are Improvised Explosive Devices (IEDs), which generate blast overpressure (BOP), fragments and heat. Personal Protective Equipment (PPE) of dismounted soldiers are primarily tested for protection against bullets, fragments, heat and stabbing using accepted formal standards. Until now

BLAST OVERPRESSURE FROM VERY-HIGH-ALTITUDE BURSTS.
1960Abstract : The objective was the measurement of time of arrival, peak overpressure, and pressure versus time at five balloon-borne canisters suspended at various distances below a low yield device (Shot Yucca) detonated at a very-high altitude. In order to circumvent telemetry blackout, the pressure data was to be stored on internal recorders and then ...

Modeling of the Non-Auditory Response to Blast Overpressure
1987Abstract : The goal of this project is to develop mathematical models of the physical processes that cause blast injury so that the results of these tests using animals in simple blast environments can be safely translated to estimating hazard to man exposed to blast both in the free field and within enclosures.

Modeling of the Non-Auditory Response to Blast Overpressure. The State of Modeling Blast Injury
1990Abstract : To understand the importance of the findings of the modeling project and to appreciate the need for extending those ideas, it is necessary to review the state of knowledge of blast overpressure injury at the time that the modeling project was initiated and how the needs of Army have evolved.
