We report results from ultrafast compression experiments conducted on β-HMX single crystals. Results consist of nominally 12 picosecond time-resolved wave profile data, (ultrafast time domain interferometry –TDI measurements), that were analyzed t

A Gurney-type equation was previously corrected for wall thinning and angle of tilt, and now we have added shock wave attenuation in the copper wall and air gap energy loss. Extensive calculations were undertaken to calibrate the two new energy loss

The dynamic mechanical behavior characterization of epoxy-cast stoichiometric mixtures of nano- or micron-scale aluminum and hematite (Fe2O3) powders is investigated in this work. Experiments conducted on rod-shaped samples, using instrumented revers

A Hertzian-based elastic/plastic hardness stress–strain analysis is employed to demonstrate that, for low temperature indentation measurements made on hard single crystals and polycrystals, the elastic and plastic indentation strains are of compara

Continuous indentation tests are now commonly used to measure the elastic moduli of materials in accordance with the unloading response of a plastic indentation. However, a previous technique utilizing a Hertzian ball indentation test, applied to the

Two-phase TiB2+Al2O3 ceramics with an interconnected or dispersed TiB2 (minor)-phase microstructure can be produced by variations in processing parameters. A standard method of quantitative characterization of the microstructural bias, i.e., the degr

The dynamic high-strain-rate behavior of two-phase TiB2+Al2O3 ceramics with biased microstructures was investigated in this study. The microstructural bias includes differences in phase (grain) size and phase distribution such that in one case a cont

Digital image correlation (DIC) was used as a diagnostic tool in two series of scaled explosive experiments. In this paper, we focus on the use of DIC as a tool to obtain full-field displacement measurements during high-speed events. From the displac

A new gas gun capability designed for the velocity range of ~20-400 m/s was used to study the mechanisms of low-velocity impact ignition and reaction violence of explosive targets in safety studies. Hemispherical charges of the HMX-based explosive LX

The motivation for the current study is to evaluate the dynamic loading response of an inert mock explosive material used to replicate the physical and mechanical properties of LX-17-1 and PBX 9502 insensitive high explosives. The evaluation of dynam
