Available in PDF, EPUB and Kindle. Book excerpt: Crater measurements from approximately 1800 shots in more than 20 media with charge weights ranging from less than 1 lb to 320,000 lb were analyzed to: (a) gain a better understanding of the problems involved in determining the shape and size of craters formed by high explosives; (b) establish the order of variation that characterizes cratering data; and (3) develop improved and/or more generalized techniques for predicting crater dimensions. Scaling trends for shots fired on or under the ground are determined from plots of crater radius and depth as a function of charge weight. By means of the least-squares procedure, the equation of the line best fitting the data was determined, along with 95% confidence limits, thereby establishing empirically the scaling laws that relate crater size and charge weight. The well-known cube-root scaling law is not entirely acceptable for scaling all dimensions of a crater; apparently this law varies with the type of medium being cratered and the charge weight and position. Curves are presented to assist in predicting crater size and shape for charges up to 1,000,000 lb of TNT. Also, the influence of various soil types on crater size is shown graphically.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Analogies between nuclear and conventional excavations are developed from a tabulation of data from 153 mine, quarry, roadway, and dam excavations. The following factors were used as the basis for tabulation of conventional excavation data: purpose, location, precipitation, temperature, ground water level, lithology, mass strength, structural pattern, slope plan, slope profile, depth of excavation, slope height, average inclination, and stability. It was found that average slope inclination tends to be greatest for hard material and for material lacking a well-developed structure, and that inclination tends to de- crease with increasing slope height for excavated slopes reported to be stable. The authors conclude that good analogies are to be found in shape, slope height, depth of excavation, and slope inclination. Loadings of waste material at the rim of some open pit mines may be analogous to ejecta on the lips of nuclear craters. Rubble zones found in some open pit mines may be analogous to the fallback zones of nuclear craters. Differences between preshot and postshot characteristics of cratered media must be appreciated in evaluating analogies between features of conventional excavations and preshot features of nuclear excavation sites. Brief descriptions of 21 selected excavations are presented in Appendix A. The results of this study serve as an aid to judgment of nuclear crater slope stability. Potential subjects for further study are identified.

Download or read book Numerical Analysis and Modelling of Composite Materials written by J.W. Bull and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Composite materials are increasingly used in many applications because they offer the engineer a range of advantages over traditional materials. They are often used in situations where a specified level of performance is required, but where the cost of testing the materials under the extremes of those specifications is very high. In order to solve this problem, engineers are turning to computer Modelling to evaluate the materials under the range of conditions they are likely to encounter. Many of these analyses are carried out in isolation, and yet the evaluation of a range of composites can be carried out using the same basic principles. In this new book the editor has brought together an international panel of authors, each of whom is working on the analysis and Modelling of composite materials. The overage of the book is deliberately wide; to illustrate that similar principles and methods can be used to model and evaluate a wide range of materials. It is also hoped that, by bringing together this range of topics, the insight gained in the study of one composite can be recognized and utilized in the study of others. Professional engineers involved in the specification and testing of composite material structures will find this book an invaluable resource in the course of their work. It will also be of interest to those industrial and academic engineers involved in the design, development, manufacture and applications of composite materials.
