It has long been known that trapped gas between an impactor and high explosive will precompress a layer of the explosive. Most quantitative studies measure the resulting decrease in shock sensitivity. There have been no studies really aimed at measur

Continuous release isentropes for the plastic-bonded explosive PBX-9501 are obtained from velocity interferometer system for any reflector measurements at a high-explosive/LiF interface. Forward calculations from a tabular representation of the isent

Sound speeds, at pressure, and the overdriven Hugoniot were measured for the plastic‐bonded explosive PBX‐9501. The two curves intersect at the Chapman–Jouguet (CJ) state because of the sonic condition D=c+u. This permitted a novel determinatio

New high‐pressure shock‐wave data have been obtained for W and Mo. These data have been combined with previous data sets for these materials to extend the range of linear us–up fits for the Hugoniot to 480 GPa for Mo and 680 GPa for W. The shoc

A definitive set of the Los Alamos Hugoniot data for iron in a pressure regime extending to 442 GPa is given. Earlier standards data, obtained using conventional explosive systems, were thoroughly reprocessed. All original film records were reread. O

We report here on a collection of shock compression experiments on a silicon polymer foam with varying degrees of distension from low (∼0.4 g/cm3) to the near fully dense material (∼ 1 g/cm3). These experiments are being carried out on a two‐st

To a first approximation, the effect of isotope exchange on the Hugoniot of a material can be represented by a scaling of the density in Ph(V). For deuterated polyethylene, this approximation is adequate to the accuracy of the data. Data for deuterat

Experiments have been done to obtain product isentropes of the plastic bonded TATB explosive PBX 9502. A thin aluminum flyer was thrown at an explosive disk so as to generate a state in excess of the Chapman-Jouguet pressure. Because the flyer is thi

When thin flyer plates are used to shock initiate high explosive (HE), any air present ahead of the flyer may cause a significant desensitization of the HE. The effect of the air in cushioning the impact of plastic flyers faced with metal films is an

We show the failure of the standard Jones-Wilkins-Lee (JWL) equation of state (EOS) in modeling the overdriven release experiments of PBX 9501. The deficiency can be tracked back to inability of the same EOS in matching the shock pressure and the sou
