Transient Response of Miniature Piezoresistive Pressure Sensor Dedicated to Blast Wave Monitoring

Sensors, 2022
Blast waves generated by energetic materials involve very fast time variations in the pressure. One important issue for blast wave metrology is the accurate measurement (typical precision in the range of ±5% or better) of the static overpressure peak ...

Assessment of the Effectiveness of Combat Eyewear Protection Against Blast Overpressure [PDF]

Journal of Biomechanical Engineering, 2018
It is unclear whether combat eyewear used by U. S. Service members is protective against blast overpressures (BOPs) caused by explosive devices. Here, we investigated the mechanisms by which BOP bypasses eyewear and increases eye surface pressure. We performed experiments and developed three-dimensional (3D) finite element (FE) models of a head form ...

Blast characteristics of center-initiated cylindrical charge in high-altitude environments

AIP Advances
The effects of different high-altitudes on the blast parameters—including peak overpressure and specific impulse—produced by a center-initiated cylindrical charge (CC) were simulated using the AUTODYN software and analyzed through dimensional analysis ...

Effects of orientation and distance of goats on blast lung injury characteristics on a plateau above 4500-meter

Chinese Journal of Traumatology, 2023
Purpose: High explosives are used to produce blast waves to study their biological effects. The lungs are considered as the critical target organ in blast-effect studies.

Inuence of Foam Filling on Dynamic Response of Hemispherical Shell Subjected to Blast Pressure. [PDF]

, 2013
The paper aims to investigate the effect of aluminium foam filling of hemispherical steel shell on its dynamic response, accounting for the blast pressure modelling. The considered structures subjected to uniformly distributed pressure, rigidly connected

Observations from Preliminary Experiments on Spatial and Temporal Pressure Measurements from Near-Field Free Air Explosions [PDF]

, 2015
It is self-evident that a crucial step in analysing the performance of protective structures is to be able to accurately quantify the blast load arising from a high explosive detonation.
