Download or read book Cratering Characteristics of Wet and Dry Sand written by Charles V. Fulmer and published by . This book was released on 1965 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirty-seven 1-lb spheres of TNT were individually exploded at various depths of burst in a sand test pad. Of these, 19 detonations were conducted in a dry sand-medium and 18 in a wet-sand medium at comparable depths of burst. The craters produced were accurately surveyed by using a bridge and probe assembly. The result of these crater surveys are shown on topographic maps. In addition to topographic measurements, volumetric measurements of the craters, ejecta measurements, and medium density, moisture content, grain size distributions are presented. The experimental procedures, equipment test area, and sand medium are discussed in detail. The comparison of crater characteristics of wet- and dry-sand environments are discussed and the results presented in tables and graphs. In addition to the crater characteristics, the formation of intracone structures, shock-agglutinated missiles, and the reduction in size of the sand grains composing the medium are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: The influence of a shallow water table on crater shapes and sizes in various types of soils was investigated. Tests using high-explosive charges ranging from 1 to 322 pounds were conducted at four separate sites. Site 1 was a specially constructed sand basin with a variable water table level. Site 2 was a natural sandbar of the Mississippi River near Vicksburg. Site 3 was on a natural sand site in central Florida, and Site 4 was a layered clay/sand site at Camp Shelby, Mississippi. Results showed that craters of drastically different shapes can be formed in the presence of a near-surface water table if the water table is in a highly saturated, loose, granular material. Wide, shallow craters were caused by soil liquefaction in loose, saturated, fine medium-loose sands; however, in a relatively dense sand that was not fully saturated, craters were 5 to 10 percent smaller in radius and depth than normal (in homogeneous soil), but still regular and bowl-shaped. In a clay/sand environment, craters tended to be about 10 to 15 percent wider than normal because of sloughing crater slopes of soft clay caused by the shallow water table in the sand. (Author).

Download or read book Geotechnical Centrifuge Modeling of Explosion Induced Craters written by Deborah J. Goodings and published by . This book was released on 1988 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: One hundred twenty-one model tests of explosion induced craters in dry sand were conducted using small charges of PETN detonated at accelerations between 1g and 101g; ninety-six were found to be useful in analysis. Extrapolation to prototype dimensions indicates that for half-buried charges, crater volume, V, is a function of explosive weight, W to the 0.84 power, and crater radius and depth are functions of W to the 0.28 power. There were no detectable acceleration related scale effects from 31g to 101g. This confirms the value of the geotechnical centrifuge in modelling explosion induced craters at less than 100 g provided attention is paid to certain test conditions and scale effects. These include soil particle size, and angularity and soil strength which appear to strongly affect model crater volume and shape. Crater volume is also very sensitive to the unit weight of dry sand and to a lesser degree to charge location, geometry and orientation. Boundary effects arising from model dimensions and the centrifuge enclosure were examined. Keywords: Cratering, Model test extrapolation, Half buried high explosives. (EDC).
