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

open access: yesFrontiers 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.

Transition Between Regular Reflection and Mach Reflection in the Dual-Solution Domain [PDF]

open access: yes, 2007
A study of the shock-reflection domain for steady flow is presented. Conditions defining boundaries between different possible shock-reflection solutions are given, and where possible, simple analytic expressions for these conditions are presented. A new,

Detonation Induced Strain in Tubes [PDF]

open access: yes, 2010
When a detonation wave propagates through a piping system, it acts as a traveling pressure load to the pipe wall. The detonation wave must be followed by an expansion wave in order to bring the combustion products to zero velocity at the ignition end ...

Detonation Diffraction in Mixtures with Various Degrees of Instability [PDF]

open access: yes, 2005
Planar laser induced fluorescence (PLIF) is widely used in combustion diagnostics but has only recently been successfully applied to detonation. The strong spatial variations in temperature, pressure, and background composition under these conditions ...

The immersed-body gas-solid interaction model for blast analysis in fractured solid media [PDF]

open access: yes, 2016
Blast-induced fractures are simulated by a novel gas-solid interaction model, which combines an immersed-body method and a cohesive zone fracture model. The approach employs a finite element fluid model and a combined finite-discrete element solid model.

Understanding the Mechanics of Blast Pressure Waves Inside a Shock-Tube: Effects of Geometry Optimization on the Blast Profile

open access: yes, 2017
While many theoretical and numerical studies have been carried out to study blast induced traumatic brain injury (bTBI), validation of simulation results is still a concern due to moral issues and experimental constraints.

The aerodynamics of curved jets and breakaway in Coanda flares [PDF]

open access: yes, 1991
An investigation was carried out into external-Coanda Effect flares designed by British Petroleum International plc. The phenomenon of interest was breakaway of an under expanded axisymmetric curved wall jet from the guiding surface due to high blowing ...

Field Experiments and Numerical Analysis of the Ground Vibration Isolation of Shock Wave Propagation under Explosion Shock Loading

open access: yes, 2019
Because blast effects can jeopardize the safety of facilities, controlling blast hazards is critical in engineering design and construction. The attenuation and amplification effects generated by blast waves are affected by the topography and terrain of ...

Safe dynamic design of structures. [PDF]

open access: yes, 2000
The Design of structures under dynamic loading is a demanding subject in safety of engineering design since conventional static failure criteria are unable to deal with structures under transient loading.

Plane blast wave interaction with an elongated straight and inclined heat-generated inhomogeneity

open access: yes, 2018
The unstable evolution of an elongated elliptically shaped inhomogeneity that is embedded in ambient air and aligned both normal and at an angle to an incident plane blast wave of impact Mach number 2.15 is investigated both experimentally and ...
