Available in PDF, EPUB and Kindle. Book excerpt: The effects of heavy steel confinement on the shock sensitivity of pressed solid high explosives heated to temperatures close to thermal explosion conditions were quantitatively measured. Cylindrical flyer plates accelerated by a 101 mm diameter gas gun impacted preheated explosive charges containing multiple embedded manganin pressure gauges. The high explosive compositions tested were LX-04-01 (85 wt.% HMX and 15 wt.% Viton A) heated to 170 ° C and LX-17 (92.5 wt.% TATB and 7.5 wt.% Kel-F) heated to 250 ° C. Ignition and Growth reactive flow models for heated, heavily confined LX-04-01 and LX-17 were formulated based on the measured pressure histories. LX-17 at 250 ° C is considerably less shock sensitive when confined by steel than when confined by aluminum or unconfined. LX-04-01 at 170 ° C is only slightly less shock sensitive when confined by steel than when it is unconfined. The confinement effect is smaller in LX-04-01, because HMX particle growth i s much less than that of TATB.

Available in PDF, EPUB and Kindle. Book excerpt: It seems that there is no book that treats the measurement of the physical pa rameters of explosives as its only subject, although limited information is avail able in a number of books. Therefore, I have tried to bridge this gap in the lit erature with this book. A large number of various physical parameters have to be determined ex perimentally in order to test or characterise an explosive. Various physical principles have been applied for such measurements. Accordingly, a large number of different experimental methods exist, as well as various testing appa ratuses and procedures. On the other hand, great progress has been made recently in the study of detonation phenomena. New measuring techniques can assess extremely short processes to below nanoseconds scale. They make it possible to determine im portant parameters in detonation physics. I have made a great attempt to cover the available literature data on the subject. Because it would be a highly demanding task to include in a single volume all the methods that are in use by various testing agencies, I have tried to give primarily the principles for determination of individual physical pa rameters of explosives by different measuring methods as well as data treatment procedures.

Download or read book Shock Sensitivity of Solid Explosive Substances with the Consideration of Explosion Transmission written by I. S. Klochkov and published by . This book was released on 1973 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well known that at an impact on an explosive substance an explosive decomposition produced by the impact is not always converted into a self-propagating explosive process; an explosion often dies out and a kind of microexplosion takes place. It appeares that explosive substances differ substantially in their ability to cause explosion propagation and, in particular, in the probability of transmitting an explosion from the substance compressed by the impact to the surrounding materials. A description is given of the experiments on the determination of conditions on which the probability of explosion transmission depends. On the basis of these investigations, a method was developed for the determination of impact sensitivity and the sensitivity measurement was performed for certain substances. (Author).

This book was released on 2012-12-06 with total page 756 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents a collection of lectures presented at the NATO Advanced study Institute(ASI) on "Chemistry & Physics of the Molecular Processes in Energetic Materials", held at Hotel Torre Normanna, Altavilla Milicia, Sicily, Italy, September 3 to 15, 1989. The institute was attended by seventy participants including twenty lecturers, drawn from thirteen countries. The purpose of the institute was to review the major ad vances made in recent years in the theoretical and experi mental aspects of explosives and propellants. In accordance with the format of the NATO ASI, it was arranged to have a relatively small number of speakers to present in depth, re view type lectures emphasizing the basic research aspects of the subject, over a two week period. Most of the speakers gave two lectures, each in excess of one hour with addition al time for discussions. The scope of the meeting was limit ed to molecular and spectroscopic studies since the hydro dynamic aspects of detonation and various performance crite ria of energetic materials are often covered adequately in other international meetings. An attempt was made to have a coherent presentation of various theoretical, computational and spectroscopic approaches to help a better understanding of energetic materials from a molecular point of view. The progress already made in these areas is such that structure property (e. g.

Book excerpt: The goal of this project is to calculate the amount of shocking or jostling that a solid explosive can withstand before detonating. The ultimate objective is to determine, by means of the calculations, how to modify the explosive so that it still retains all of its explosive power but becomes less sensitive to shock. These less sensitive but equally powerful explosives would reduce the number of accidents that occur among personnel involved in handling, storing, transporting, and using the explosives. The detonation process is complicated and involves many factors, including hot spots, propagation of acoustic or detonation waves, interaction (or scattering) between detonation waves and explosive molecules, etc. However, the key factor in an explosive's sensitivity to shock is the activation energy of the molecules that make up the explosive. When an explosive receives a shock, the energy of the molecules contained in the explosive is increased. In the region of the shock, if the energy of a sufficient number of molecules is raised above the activation energy, then the detonation begins.

This book was released on 2009-12-16 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: Los Alamos National Laboratory is an incredible place. It was conceived and born amidst the most desperate of circumstances. It attracted some of the most brilliant minds, the most innovative entrepreneurs, and the most c- ative tinkerers of that generation. Out of that milieu emerged physics and engineering that beforehand was either unimagined, or thought to be f- tasy. One of the ?elds essentially invented during those years was the science of precision high explosives. Before 1942, explosives were used in munitions and commercial pursuits that demanded proper chemistry and con?nement for the necessary e?ect, but little else. The needs and requirements of the Manhattan project were of a much more precise and speci?c nature. Spatial and temporal speci?cations were reduced from centimeters and milliseconds to micrometers and nanoseconds. New theory and computational tools were required along with a raft of new experimental techniques and novel ways of interpreting the results. Over the next 40 years, the emphasis was on higher energy in smaller packages, more precise initiation schemes, better and safer formulations, and greater accuracy in forecasting performance. Researchers from many institutions began working in the emerging and expanding ?eld. In the midst of all of the work and progress in precision initiation and scienti?c study, in the early 1960s, papers began to appear detailing the ?rst quantitative studies of the transition from de?agration to detonation (DDT), ?rst in cast, then in pressed explosives, and ?nally in propellants.

Book excerpt: The thermal sensitivity test, was applied to a number of energetic solids and liquids, including some new and unusual compounds. The correlation between the temperature at which a solid organic explosive reacts in 250 microsec and the materials impact sensitivity was extended and supported by new experimental data. The thermal sensitivities of a number of energetic mixtures were determined and interpreted on the basis of the kinetics and heat output of the initiating decomposition reaction. A scale of thermal sensitivities for liquid explosives and propellants was established and considered on the basis of current understanding of the sensitivity of liquids. Although the thermal sensitivity results generally do not agree with the results of accepted sensitivity tests, it is recommended that thermal sensitivities be run on newly synthesized, energetic liquids. The meaning of the thermal sensitivity results in terms of Arrhenius parameters governing the initial stage of the explosive decomposition reaction is considered briefly.

Available in PDF, EPUB and Kindle. Book excerpt: The complicated relations and interdependence of the various critical parameters are demonstrated. In particular, the critical diameter is determined by charge temperature, initial particle size, density, confinement, composition, and shock sensitivity. The critical initiating pressure is also a multivariant function and depends on the same set of variables. Relations between different gap (shock sensitivity) test results and between those of gap and wedge tests are also shown. (Author).
