Book excerpt: The oblique impact sensitivity of UK-UK-simulated HMX in 85 to 90% formulation with Viton is not enough lower, if any, to encourage richer formulations or change to Bridgewater processes for this reason alone. Fifty-pound cyclotol 75/25 hemispheres gave moderate reactions (No. 4) as low as 3.5 foot (14°); lower tests have not been performed yet. {open_quotes}Reduced-H.E.{close_quotes} pieces of PBX 9404, 2, 3, 4, and 5 inches thick, respectively, were tested at 1.75 foot (14°) resulting in a 6 reaction for the 5 inches thick piece while the remaining three pieces gave 0 reactions.

Book excerpt: RX-04-CW, LX-07-1, and RX-09-CD were tested. The RX-04-CW and LX-07-1 are not complete; however, results so far show the TX-04-CW comparable in sensitivity to PBX 9404 while the LX-07-1 is less sensitive at 14°. The RX-09-CD was slightly more sensitive than the RX-09-CB previously tested.

Download or read book Test Methods for Explosives written by Muhamed Suceska and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 235 pages. 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 Parallel Oblique Impact on Thin Explosive Samples written by and published by . This book was released on 1994 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The shearing of explosive materials under pressure is an effective way to produce localized heating by viscoplastic work concentrated in a small region of the deforming explosive. This localized heating can cause the explosive to react releasing additional heat to accelerate the reaction. In an earlier paper, we described the results obtained when a small cylinder of explosive was pressurized within heavy steel confinement and then allowed to slide against the steel confinement (Boyle, Frey, and Blake 1989); in a similar arrangement, we investigated explosive on explosive shear by punching a plug from the pressurized explosive cylinder. In those experiments, we demonstrated that the ignition threshold depends on both pressure and shear velocity. Those experiments had a relatively long duration of about 1 ms, a maximum pressure of about 1.0 GPa, and a maximum shearing velocity of about 80 m/s; the pressure and shear velocity varied during the course of the experiment. The rise time to peak pressure was several hundred microseconds. Also the shear localization was not well defined so the local strain rate could not be determined. In the experiments reported here, we have attempted to study the ignition of several explosives as they were impacted under conditions that would cause the explosive sample to shear in a known manner under the high pressure of the impact. A maximum pressure of 1.3 GPa was reached with a strain rate of about 50,000 per second over an explosive layer 0.6 mm thick.

Available in PDF, EPUB and Kindle. Book excerpt: A purpose of science is to organize diversified factual knowledge into a coherent body of information, and to present this from the simplest possible viewpoint. This is a formidable task where our knowledge is incomplete, as it is with explosions. Here one runs the risk of oversimplification, naivete, and incom pleteness. Nevertheless a purpose of this work is to present as simply as possible a general description of the basic nature of explosions. This treatise should be of interest to all who are working with explosives such as used in construction or in demolition work, in mining operations, or in military applications. It should also be of interest to those concemed with disasters such as explosions or earthquakes, to those involved in civil defense precautions, and to those concemed with defense against terrorists. That is, this material should be of interest to all who wish to utilize, or to avoid, the effects of explosions as weil as to those whose interest is primarily scientific in nature.
Download or read book High Velocity Impact Sensitivity of Commercial Slurry and Emulsion Explosives written by A. Bauer and published by . This book was released on 1986 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of high velocity impact initiation of commercial explosives was modelled numerically by means of a reactive hydrodynamic code in conjunction with the Forest fire model. Coefficients for the Forest fire model were determined from the Pop plots resulting from a series of wedge tests for each explosive investigated. Data for the reactive hydrodynamic code include the HOM equation of state parameters and Hugoniots. Predicted results for projectile impact were compared with the experimental results obtained for the same explosive compositions. For a given projectile the agreement between the predicted values of impact velocity beyond which detonation would occur and the observed experimental values was good.
