Measurement of Blast Waves from Bursting Pressureized Frangible Spheres [PDF]

Small-scale experiments were conducted to obtain data on incident overpressure at various distances from bursting pressurized spheres. Complete time histories of blast overpressure generated by rupturing glass spheres under high internal pressure were ...

A Multiscale Approach to Blast Neurotrauma Modeling: Part II: Methodology for Inducing Blast Injury to in vitro Models [PDF]

, 2012
Due to the prominent role of improvised explosive devices (IEDs) in wounding patterns of U.S. war-fighters in Iraq and Afghanistan, blast injury has risen to a new level of importance and is recognized to be a major cause of injuries to the brain ...

Temporal changes of neurobehavior in rats following varied blast magnitudes and screening of serum biomarkers in early stage of brain injury

Scientific Reports
Blast neurotrauma has been linked to impairments in higher-order cognitive functions, including memory, attention, and mood. Current literature is limited to a single overpressure exposure or repeated exposures at the same level of overpressure.

Altered expression of aquaporin 1 and aquaporin 5 in the cornea after primary blast exposure

Molecular Vision, 2019
Purpose: Our study aimed to determine whether the altered expression of biomarkers linked to corneal injuries, such as the edema-regulating proteins aquaporin-1 and aquaporin-5 (AQP1 and AQP5), occurred following primary blast exposure. Methods: Adult

A multiscale approach to blast neurotrauma modeling: Part I - Development of novel test devices for in vivo and in vitro blast injury models

Frontiers in Neurology, 2012
The loading conditions used in some current in vivo and in vitro blast-induced neurotrauma models may not be representative of real-world blast conditions.

Propulsion system ignition overpressure for the Space Shuttle [PDF]

Liquid and solid rocket motor propulsion systems create an overpressure wave during ignition, caused by the accelerating gas particles pushing against or displacing the air contained in the launch pad or launch facility and by the afterburning of the ...

The effects of strong shock waves on mortality rates and percentages of pulmonary lesions in rats as a function of the number of exposures [PDF]

The results of the study reveal that with regard to the pulmonary lesions, twice the number of exposures is compensated for by quartering the overpressure of the wave crest.

Investigation of Blast Resistance Performance in Reinforced Concrete Slabs Using CONWEP-ALE Coupling Algorithm

Applied Sciences
The Conventional Weapons Effects Program (CONWEP) algorithm often lacks sufficient accuracy in predicting blast responses of reinforced concrete (RC) slabs, while the Arbitrary Lagrangian–Eulerian (ALE) algorithm demands prohibitively high computational ...
