Detonation velocities and wave front curvatures are measured on various diameter cylinders of PBXN-111 (RDX/AP/Al/HTPB binder with 20/43/25/12 weight percent). The cylinders are either unconfined or encased in 5-mm-thick brass tubes. In all experimen

A porous solid's initial state is off the thermodynamic surface of the solid to start with but when pressure is high enough to cause total pore collapse or crush up, the final states are on the thermodynamic surfaces. The Hugoniot for the fully compa

A light gas gun has been used to measure the Hugoniot of Metglass 2605CO ribbon. Quartz gauges were used to measure stress. Both front‐ and rear‐surface measurements were done. Front‐surface experiments impacted the ribbon onto quartz gauges, w

For the explosive PBXN-103, multiple gauge gas gun experiments were performed to obtain Hugoniot and Lee-Tarver reactive rate law parameters. Simulations based on these parameters produced pressure histories in good agreement with measured pressure h

Shock polar theory is used to calculate the angles detonation fronts make with the cylinder wall for brass cased and bare PBXN-111 cylinders. Two extrapolated unreacted PBXN-111 Hugoniot curves are used to calculate these angles. Measured and calcula

Detonation velocities and wave front curvatures were measured for PBXN-111 charges encased in 5 mm thick brass tubes. In all the experiments (charge diameters from 19 to 47 mm) the brass case affected the detonation properties of PBXN-111. Steady det

Multiple in situ manganin gauge experiments were performed on explosive compositions IRX-1, IRX-3A, PBXN-111 (PBXW-115), and PBXN-110 (PBXW-113). For most explosives, stress-time profiles show substantial reaction. These profiles are compared to thos

Detonation velocities and wave front curvatures were measured for bare cylindrical charges of IRX-4 and PBXN-110 charges. Steady detonation waves propagated in IRX-4 charges with diameters as small as 33 mm. The failure diameter of IRX-4 is between 2
