Fragmentation and reaction of structural energetic materials
Structural energetic materials (SEM) are a class of multicomponent materials which may react under various conditions to release energy. Fragmentation and impact induced reaction are not well characterized phenomena in SEMs. The structural energetic systems under consideration here combine aluminum …

Energetic Path Finding Across Massive Terrain Data
Before there were airplanes, cars, trains, boats, or bicycles, the primary means of transportation was on foot. Unfortunately, many of the trails used by ancient travelers have long since been abandoned. We present a software tool which can help visualize and predict where these forgotten trails …

Energetic particles in the earth's magnetospheric cusps
… answer the question, what is the source of the energetic particle population in the cusp? Since the initial observations measuring the energetic component were made, the source of the energetic population has been open to conjecture. A number of sources have been proposed: (1) the terrestrial …

A Continuum Thermomechanical Model for Energetic Materials
The model is then simplified to a set of three model problems: the constant-volume thermal explosion, one-dimensional shear loading, and one dimensional longitudinal loading. These model problems were solved numerically using essentially non-oscillatory and total variation diminishing methods. The …

Enhancing reactivity of aluminum-based structural energetic materials
… aluminum casings expend little of the energetic potential stored within the material. In addition, aluminum casings are capable of producing large fragments (on the order of mm's) which can be diffi cult to ignite and are accelerated away from the target, lending no additional reaction …
