Available in PDF, EPUB and Kindle. Book excerpt: Aspects of cratering phenomenology are considered along with material properties and shock effects, theoretical cratering mechanics, ejecta, and problems of scaling. Attention is given to the application of high explosion cratering data to planetary problems, cratering mechanisms observed in laboratory-scale high-explosive experiments, nuclear cratering experiments, complex craters in alluvium, terrestrial impact structures, the Ries impact crater, buried impact craters in the Williston basin and the adjacent area, crater morphometry from bistatic radar, a Fourier analysis of planimetric lunar crater shape, a stratigraphic model for Bessel Crater and southern Mare Serenitatis, a nested-crater model of lunar ringed basins, Martian fresh crater morphology and morphometry, the distribution and emplacement of ejecta around Martian impact craters, the nature of the present interplanetary crater-forming projectiles, cratering mechanics and future Martian exploration, the response of rocks to large stresses, the dynamical implications of the petrology and distribution of impact melt rocks, and a review and comparison of hypervelocity impact and explosion cratering calculations.

Download or read book Scaling Dimensions of Craters Produced by Buried Explosions written by Albert J. Chabai and published by . This book was released on 1965 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question of the proper scaling of crater dimensions resulting from buried explosions is investigated. Dimensional analyses are performed from which four different scaling rules are derived. Data are reviewed in an attempt to distinguish which scaling rules are fundamental to cratering. Inability to perform cratering experiments with similitude apparently is one reason for lack of an unambiguous answer to the scaling question. Influences of possible sources of similarity violation are qualitatively examined, and some experiments are suggested which may provide more direct information about the correct scaling of crater dimensions.

Download or read book The Encyclopedia of Field and General Geology written by Charles W. Finkl and published by Springer Science & Business Media. This book was released on 1988-04-30 with total page 868 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field work, supplemented by laboratory studies, is a cornerstone for the geological sciences. This volume provides an introduction to general field work through selected topics that illustrate specific techniques and methodologies. One hundred and twenty-three main entries prepared by leading authorities from around the world deal with aspects of exploration surveys, geotechnical engineering, environmental management. field techniques, mapping, prospecting, and mining. Special efforts were made to include topics that consider aspects of environmental geology in particular those subjects that involve field inspections related to, for example, the placement of artificial fills, sediment control in canals and waterways, the geologic effects of cities, or the importance of expansive soils to environmental management and engineering. In addition, some widely ranging topics dealing with legal affairs, geological methodology, the scope and organization of geology, report writing, and other concepts, such as those related to plate tectonics and continental drift, provide a necessary perspective to the arena of field geology.

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).

This book was released on 1970 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current knowledge of the physical effects of underwater explosions on the environment is summarized, with particular attention to the heating of water, the mixing of explosion products with water, and cratering. Theory and data indicate that thermal effects on the environment are negligible because rapid turbulent mixing reduces any temperature excess to a negligible amount within minutes. Virtually no data are available on the mixing of explosion products with water and air. However, information on the bubble and surface phenomena of underwater explosions has been utilized to provide qualitative guidance concerning the distributions immediately after a test. Existing theories of turbulent diffusion can be applied to calculate the subsequent history of the products. Knowledge of the physical effects of bottom explosions on the environment is limited to crater measurements in shallow water and some data on the behavior of explosion bubbles in deep water. Suggested programs to fill gaps in current knowledge are outlined. (Author).
