Available in PDF, EPUB and Kindle. Book excerpt: The research presented examines DDT of cylinders of PBX 9501 damaged above 180 C in heavy confinement for 0-3 hours and end-ignited or ramped until self-ignition (cookoff) occurred. Progression of luminous reaction was observed by streak photography through a glass-filled slit running the length of the cylinder. Post-mortem analysis of the steel DDT tubes was also done for correlation with the optical records. Results indicate that repeatable, Type I DDT was observed to occur in hot, thermally damaged PBX 9501 with low levels of porosity. It was demonstrated that multiple parameters affect DDT behavior, most likely in a coupled fashion. These parameters are porosity, ignition temperature and thermal soak duration. Conditions leading up to cookoff were shown to sensitize the HE to DDT by increasing likelihood and decreasing run length. Over the range of porosities (0-37%) and ignition temperatures (180-235 C), run lengths and detonation velocities varied, respectively, from approximately 22-109 mm and 6.0-8.3 mm [mu]s−1. This work fills a valuable and realistic space in the understanding of high explosive violent reaction, including DDT, in abnormal thermal environments.
Book Synopsis Violent Reactions and DDT in Hot, Thermally Damaged HMX-Based PBXs by :
Download or read book Violent Reactions and DDT in Hot, Thermally Damaged HMX-Based PBXs written by and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional high explosives (e.g. PBX 9501, LX-07) have been observed to react violently following thermal insult: (1) Fast convective and compressive burns (HEVR); (2) Thermal explosions (HEVR); and (3) Deflagration-to-detonation transition (DDT). No models exist that sufficiently capture/predict these complex multiphase and multiscale behaviors. For now, research is focused on identifying vulnerabilities and factors that control this behavior.
Book Synopsis Deflagration Behavior of PBX 9501 at Elevated Temperature and Pressure by :
Download or read book Deflagration Behavior of PBX 9501 at Elevated Temperature and Pressure written by and published by . This book was released on 2008 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report the deflagration behavior of PBX 9501 at pressures up to 300 MPa and temperatures of 150-180 C where the sample has been held at the test temperature for several hours before ignition. The purpose is to determine the effect on the deflagration behavior of material damage caused by prolonged exposure to high temperature. This conditioning is similar to that experienced by an explosive while it being heated to eventual explosion. The results are made more complicated by the presence of a significant thermal gradient along the sample during the temperature ramp and soak. Three major conclusions are: the presence of nitroplasticizer makes PBX 9501 more thermally sensitive than LX-04 with an inert Viton binder; the deflagration behavior of PBX 9501 is more extreme and more inconsistent than that of LX-04; and something in PBX 9501 causes thermal damage to 'heal' as the deflagration proceeds, resulting in a decelerating deflagration front as it travels along the sample.

Book Synopsis High-Pressure Shock Compression of Solids IV by : Lee Davison
Download or read book High-Pressure Shock Compression of Solids IV written by Lee Davison and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: While much is known about the effects of shock compression on monolithic materials, the unusual physical and chemical processes that take place when a porous medium is shocked have hardly been studied until now. Here, leading researchers in condensed matter physics, physical chemistry, metallurgy, mechanics, and materials science bridge this gap. The focus is on heterogeneous deformation mechanisms, nonequilibrium thermodynamics, and chemical processes, covering such topics as modelling the complex interplay of thermal, mechanical, and chemical processes; experimental data on pore collapse and their interpretation; and synthesis of new materials through shock-induced chemical reactions. By presenting not only the most recent results, but also the open questions that remain, these essays convey the excitement of developing a scientific basis for understanding shock compression.
Book Synopsis Young People Transitioning from Out-of-Home Care by : Philip Mendes
Download or read book Young People Transitioning from Out-of-Home Care written by Philip Mendes and published by Springer. This book was released on 2016-09-26 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book challenges and revises existing ways of thinking about leaving care policy, practice and research at regional, national and international levels. Bringing together contributors from fifteen countries, it covers a range of topical policy and practice issues within national, international or comparative contexts. These include youth justice, disability, access to higher education, the role of advocacy groups, ethical challenges and cultural factors. In doing so it demonstrates that, whilst young people are universally a vulnerable group, there are vast differences in their experiences of out-of-home care and transitions from care, and their shorter and longer-term outcomes. Equally, there are significant variations between jurisdictions in terms of the legislative, policy and practice supports and opportunities made available to them. This significant edited collection is essential reading for all those who work with young people from care, including social workers, counsellors, and youth and community practitioners, as well as for students and scholars of child welfare.
Book Synopsis Explosive Shocks in Air by : Gilbert F. Kinney
Download or read book Explosive Shocks in Air written by Gilbert F. Kinney and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 281 pages. 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.
