متن کاملViscous attenuation of a detonation wave propagating in a channel
The propagation of a detonation wave remains one of the challenging problems in physics. While it is possible to predict the average propagation velocity almost correctly using classical theory [1, 2], there is no theory to explain the internal flow structure satisfactorily. The famous Zel’dovich-von Neumann-Döring theory [3, 4, 5] is widely considered to describe the one-dimensional detonation...
متن کاملStress wave attenuation in shock-damaged rock
The velocity and attenuation of ultrasonic stress waves in gabbroic rock samples (San Marcos, California) subjected to shock loading in the 2 GPa range were studied. From P wave velocity measurements we determined the damage parameter Dp and crack density e of the samples and related these to the attenuation coefficient (quality factor) under dynamic strains of 2 x 10 -? and at a frequency of 2...
متن کاملHigh Pressure Shock Wave Attenuation
The attenuation of high pressure shock waves has been investigated. High purity copper, 6061-T6 aluminum, 6A1-4V and a phase titanium, an uranium alloy and two alloys of beryllium were examined experimentally at pressures as high as 3 megabars. Low pressure experiments were instrumented with a velocity laser interferometer. Intermediate pressures (to several hundred kilobars) were instrumented ...
متن کاملEffect of phase change on shock wave attenuation in GeO2
Stress-wave profiles in vitreous GeO2 induced by planar and spherical projectile impact were measured using piezoresistance gauges in the 4 to 18 GPa shock pressure range. The planar experiments demonstrate the response of vitreous GeO2 . This response can be divided into three regimes: ~1! An elastic shock regime with ramp 4 GPa Hugoniot elastic limit ~HEL! precursor. Shock propagation velocit...
