S.j. Pierce ; W.a. Charlie ; Geotechnical engineering program colorado state university | US Department of Commerce | 1990Compressive stress wave propagation through soils is of interest to the armed forces, mining industry and geophysical investigations. Research on high amplitude, short duration compressive loadings is important in understanding the soil structur[...]

Jerry Brown ; Donald w. Murrell ; John h. Stout ; Army engineer waterways experiment station | US Department of Commerce | 1990This report describes tests conducted on shock transmitted through rubble screens from explosions on the top of the screens. The results are compared with shock transmitted through slabs and through free soil. There appears to be little differen[...]

Martin h. Sadd ; Mohammad Hossain ; Behza Rohani ; Rhode island university | US Department of Commerce | 1986This report describes an investigation into one-dimensional stress wave propagation in granular materials with microstructure. The study employs the distributed body concept advanced by Goodman and the associated wave propagation studies conduct[...]

J.d. Collins ; R.d. Daniels ; K.b. Overbeck ; J.h. wiggings company | US Department of Commerce | 1978A qualitative analysis of the effect of uncertainty on the free-field ground shock estimation process is presented. The approach is to examine the process as a modeling problem and examine each part so as to isolate uncertainties in the framewor[...]

M.a. Mikulinskiy ; P.s. Mironov ; G.v. Kuznetsov ; Foreign technology division | US Department of Commerce | 1972The report presents a study of the effect of shock waves from a controlled burst on the soil and rocks in the immediate vicinity of a burst at a quarry. It details the general equations of shock waves in soils; determination of parameters of sei[...]
