The impact damage behavior of polymer bonded explosives (PBXs) is critical to ensure the
safety of explosive systems. PBX 1314 (60 wt% RDX, 16 wt% aluminum, and 24 wt% HTPB) …

Fracture of crystals and frictional heating are associated with the formation of “hot
spots”(localized heating) in energetic composites such as polymer bonded explosives …

The acoustic emission (AE) waveforms from a fatigue crack advancing in a thin metallic plate
possess diverse and complex spectral signatures. In this article, we analyze these waveform …

Temporary and permanent macromolecular conformational changes can accompany the
deformation of elastomers under high strain rate loading. Mechanical failure can occur as …

The influences of specimen length-to-diameter ratio, material compressibility, and inertia on
direct impact response of high density closed-cell polymeric foam are investigated. High …

Dynamic deformation response of closed-cell rigid polymeric form is explored at different
length scales. This study is facilitated by ultra-high speed photography in conjunction with …

Ultra-high-speed and high spatial resolution digital image correlation based experiments
are performed to understand the sub grain level local failure mechanisms in polymer …

A damaged viscoelastic-plastic model incorporating with both microcrack and microvoid
evolution laws has been developed and implemented in the hydrodynamic code DREXH, to …

To improve the safety of ammonium nitrate explosives, the melamine urea-formaldehyde
resin (MUF resin) was selected for the preparation of three typical nitramine explosives …

Shock compression plate impact experiments conventionally rely on point-wise velocimetry
measurements based on laser-based interferometric techniques. This study presents an …
