Low-pressure Overdriven Experiments in PBX-9502


Book Description

Symmetric impact experiments were performed on PBX 9502 to obtain Hugoniot data in the low-pressure, overdriven regime. An explosive plane wave lens (P300 with comp-B booster) was used to launch an aluminum flyer plate (4 to 4.5 km/s) into an aluminum target backed by the PBX 9502 samples and a LiF window. Photonic Doppler velocimetry (PDV) was used to obtain the shock transit time through the PBX 9502 samples and wave profile data at the PBX 9502/LiF interface. Past experimental result in the overdriven regime, utilizing a rotating mirror streak camera, revealed a well-defined high-pressure Hugoniot. In contrast, the low-pressure (overdriven) data exhibited significant scatter likely due to non-steady wave effects associated with the thin PBX 9502 samples (3-5 mm) used in the experiments. The objective of the current work was to obtain Hugoniot data in the low-pressure, overdriven regime for PBX 9502 using recently developed diagnostics along with thicker samples (5-10mm) to decrease the uncertainty and scatter in the Hugoniot data.




A Study of the Overdriven Behaviors of PBX 9501 and PBX 9502


Book Description

The author presents the Hugoniot pressure and sound speed data in the overdriven regime for both PBX 9501 and PBX 9502. The overdriven release experiments are also given. The failure of the standard Jones-Wilkins-Lee equation of state in modeling both the Hugoniot data and the overdriven release experiments for both high explosives are identified and remedy is made by including additional terms to steepen the slope of the Hugoniot in the high pressure regime. However, an anomaly presented itself as a kink in the release wave of PBX 9502 is observed. A careful examination of the Hugoniot data indicates similar behavior. A possible explanation is suggested for this peculiarity to the phase transition of carbon in the products.




Future Developments in Explosives and Energetics


Book Description

The International Explosives Conference (IEC) champions cutting-edge, deep-science research conducted internationally in the energetic materials sector. Designed for professionals, academics and researchers, it is involved in the fundamental science of explosives and other energetic materials. Set firmly in the context of ‘future developments’, IEC-2022 presents and debates the themes of: energetic materials and characterisation; manufacturing and processing; response to stimuli; advances in experimental techniques and diagnostics and theory, modelling and simulation. IEC-2022 took place in London from 22 to 24 June 2022 and this publication provides a record of the proceedings for the oral presentations and display posters that were showcased at the event.

Numerical Modeling of Explosives and Propellants, Second Edition


Book Description

Charles Mader, a leading scientist who conducted theoretical research at Los Alamos National Laboratory for more than 30 years, sets a new standard with this reference on numerical modeling of explosives and propellants. This book updates and expands the information presented in the author's landmark work, Numerical Modeling of Detonations, published in 1979 and still in use today. Numerical Modeling of Explosives and Propellants incorporates the considerable changes the personal computer has brought to numerical modeling since the first book was published, and includes new three-dimensional modeling techniques and new information on propellant performance and vulnerability. Both an introduction to the physics and chemistry of explosives and propellants and a guide to numerical modeling of detonation and reactive fluid dynamics, Numerical Modeling of Explosives and Propellants offers scientists and engineers a complete picture of the current state of explosive and propellant technology and numerical modeling. The book is richly illustrated with figures that support the concepts, and filled with tables for quick access to precise data. The accompanying CD-ROM contains computer codes that are the national standard by which modeling is evaluated. Dynamic material properties data files and animation files are also included. There is no other book available today that offers this vital information.
