Figure 5. Zhang et al. Human body simulations with and without protective armor are also a future intention for investigation in future experiments. On the surface of the lungs, hemorrhagic spots could be discovered. HE detonate to produce a defining supersonic over-pressurization shock wave. Development of a finite element model of the total human model for safety THUMS and application to injury reconstruction. Stuhmiller, J. Wang, C. In order to observe blast lung injury more accurately and reliably, we implemented finite element modeling to mimic blast lung injury.

  • The detonation of a cartridge of a high explosive is started by firing a detonator, which consists of a small metal cylinder containing a compound or mixture which​. Blast injuries, including blast-induced neurotrauma (BINT), are caused by blast waves generated during an explosion. Accordingly, their history. Shock waves were recognized as a natural phenomenon more than a century ago, yet they are still not widely understood.

    They are responsible for the crash of​.
    The validation results reflected that at both sides of the lung at distances of 40—60cm, the pathological scores and the pressure levels showed strong correlations.

    Across the contact discontinuity, the pressure and velocity are continuous and the density is discontinuous. The conditions of the lung edema, hemorrhage and inflammation were each scored to stack up to a total score. August Toepler's schlieren apparatus used two lenses and a small bright lamp, flashing in the microsecond range, to project an image on a viewing screen a.

    Introduction As a result of the continuous growth of conflicts and urban terrorism, deaths caused by explosions still occur in some areas 1.

    However, this phenomenon can be controlled for medically beneficial purposes as well: A method called shock wave lithotripsy focuses shock-wave energy at a point inside the body to break up kidney stones without significantly damaging the surrounding tissue.

    The surface pressure could then be validated by real experiments. Ina biological shock tube was developed through research in China to generate blast injury Secondary blast injuries are the most common cause of mortality in victims of an explosion. Eventually Mach's name was linked to the non-dimensional ratio of an object's velocity V to the speed of sound: the Mach number.

    Offering an introductory review of historic research, Shock Waves and Explosions brings analytic and computational methods to a wide audience in a clear and. In fluid dynamics, a blast wave is the increased pressure and flow resulting from the deposition. Like other types of explosions, a blast wave can also cause damage to things and people by the blast wind, debris, and fires.

    The original.

    In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating. Examples: Balloon bursting, Shock tube, shock wave from explosion.
    The slip surface 3D or slip line 2D is a plane across which the tangent velocity is discontinuous, while pressure and normal velocity are continuous. A shock wave can be produced by the rapid forward motion of a piston in a tube.

    The calculation process started from the initial shock wave.

    We compared the measured pressure peaks of the five distances to the simulation pressure peak. Shock waves can form due to steepening of ordinary waves.

    The explosion wave could only proceed from one point to a spherical shape. Lung tissue resistance and pulmonary hysteresis.

    Though, entropy is increasing; this must be accounted for by a drop in stagnation pressure of the downstream fluid. Eur J Radiol.

    Coupled with the utility of small gram-range explosive charges, which are used for safety and convenience in research, this technology opens new vistas in the study of shock waves and explosions. Secondary blast injuries account for the majority of injuries from an explosion event. High explosives that detonate generate blast waves.
