    Notes: Summary Results are presented from a testing program to study the effect weak layers embedded in a strong rock strata have on particle velocity when subjected to explosive loading. A similar computational study had been conducted earlier with WONDY — a finite difference Langrangian code developed at Sandia National Laboratory. The experiments were conducted using models fabricated from Hydrocal containing a single dry sand layer or clay layer through which the stress wave traveled. Particle velocity was measured in front of and past the weak layer to determine attenuation, pulse shape changes, and displacement loss. The results from the model testing indicated that particle velocity amplitude decreased significantly when the stress wave passed through the weak layer. The velocity pulse width on the other hand was found to remain relatively constant when passing through the weak layer. The computational results from WONDY predicted similar behavior and hence were in good agreement with the tests. In the experiments, the velocity loss across a sand layer was found to be much larger than the loss across a clay layer. The stress wave velocity in the sand layer was found to be significantly smaller than in the Hydrocal while the experimentally determined wave velocity in the clay was nearly equal to the wave velocity in the Hydrocal.

    Notes: [Auszug] Matter accreting on to a black hole may be heated to very high temperatures and radiate g rays1,2. The accretion of matter onto a black hole can be treated as a hydrodynamic flow if a weak magnetic field is carried with the accreting gas1,3. In the hydrodynamic model the accreting gas is rapidly ...

    Effects of open gaps on particle velocity measurements (1997)

    Notes: Summary Joints and bedding planes are present in nearly all geologic media. These discontinuities vary in the extent to which they are open and the material with which they are filled. The presence of such discontinuities affect the ground motions that result from the detonation of an explosive source. The effects of these discontinuities are especially important if it is desired to predict the size of the explosive source from measurements of ground motion — such as particle velocity or stress. In this paper we present results from a series of model tests conducted to investigate the effect of open gaps on the particle velocity that can be transmitted across them. Electromagnetic velocity gages were used to record particle velocities at several locations on either side of an open gap of known width. The study was restricted to the transmission of particle velocities normal to the gap and to the case where the gap was located in a region for which the stress was high but not greatly above the elastic limit of the material. The experimental results were compared qualitatively to results obtained from WONDY — a one dimensional Lagrangian finite difference code. Although the tests were conducted in laboratory models, the results can be scaled to compare to the full scale situation.
