A 3-D Rat Brain Model for Blast-Wave Exposure: Effects …

We explicitly represented the rat''s cerebral vasculature and used high-strain-rate material properties of the rat brain. For a range of blast overpressures (100 to 230 kPa) the brain-pressure predictions matched experimental results and largely overlapped with and tracked the incident pressure-time profile.

Inelastic strain in the hypocentral region of the 2000 …

11/5/2020· Inelastic deformation due to seismic activity is an important signal that reflects fault evolution. In particular, aftershock sequences indie the evolution of damage in a medium that has experienced a large earthquake. Herein, we discuss the inelastic strain rate surrounding the fault that produced the M 7.3 Western Tottori earthquake in 2000 using long-term aftershock analysis. To obtain

A theoretical model for fragmentation of viscous bubbly magmas in shock …

magmas in shock tubes. Initially a bubbly magma at a high pressure is separated from air at the atmospheric pressure by a diaphragm. As the diaphragm is ruptured, a shock wave propagates into the air, and a rarefaction wave propagates into the bubbly magma.

Color of Shock Waves in Photonic Crystals - MIT

The shock wave propagates about 0:5a in Fig. 2, and this frequency conversion process is observed once for every lattice unit the shock wave traverses, resulting in a pulsed output for a continuous wave input. The pulse rate, typically around 1010 Hz, can be

Micro Scale Laser Shock Processing of Metallic …

Shock pressure and strain/stress are properly modeled to reflect the micro scale involved, and the high strain rate and ultrahigh pressure involved. Numerical solutions of the model are experimentally validated in terms of the geometry of the shock-generated plastic deformation on target material surfaces as well as the average in-depth strains under various conditions.

Single crystal aluminum and copper of (001) and (110) orientation were shock peened using laser beam of 12 micron diameter and observed with X-ray micro-diffraction techniques based on a synchrotron light source. The X-ray micro-diffraction affords micron level

TRAVELING WAVES AND SHOCKS IN A VISCOELASTIC …

Note that if a traveling wave exists, then it moves with the same speed as traveling waves in Burgers’ equation (1.1) and shock waves in inviscid Burgers’ equation (1.2). We obtain the equation for the velocity profile, U, by using (3.1) and (3.5) to

THE PROPERTIES OF CONCRETE MATERIALS SUBJECTED TO IMPACT AND SHOCK …

shock wave physics was published by Davison and Graham [17]. However, real solids have initial strength, which further depends on the passage of the shock wave. For instance, many metals exhibit strain and strain rate hardening as a result of disloion

The mechanochemistry in heterogeneous reactive …

Rise-time dispersive signatures are consistently observed under uniaxial strain loading, indiing complex compaction phenomena, which are reproducible by the meso-scale simulations. The simulations show the prevalence of shear banding and particle agglomeration in the uniaxial stress case, providing a possible rationale for the lower observed reaction threshold.

Shock-induced breaking of the nanowire with the …

At high strain rates, symmetric stretching in non-equilibrium state brings a large stress gradient, which induces the difficulty of shock wave propagation, so shock waves overlap at the two ends of the nanowires, which tend to break at the two ends without
