Explosive Fragmentation of a Thin Ceramic Tube Using Pulsed Power

Explosive Pulsed Power: An Enabling Technology

Explosive pulsed power consists of those devices that convert the chemical energy in explosives into electrical energy. In 2004, a series of programs were initiated to develop several types of very compact explosive pulsed power generators. Based on these recent efforts, we now have a better understanding of the weaknesses and strengths of these small generators. As a result, we can now build r...

Effect of Impact Parameters on Explosive Welding of Tube to a Plug

Effects of some important parameters like impactor effects, plug geometry and initiation points on bonding aluminum tubes to aluminum plugs were studied. The impact velocity and dynamic angle between tube and plug should be precisely managed to achieve an optimum bonding condition. A new explosive bonding technique with the use of two material impactors was proposed. Results are especially suit...

A theoretical model of the explosive fragmentation of vesicular magma

Recent experimental work has shown that, when a vertical column of rock under large pressure is suddenly depressurized, the column can ‘explode’ in a structured and repeatable way. The observations show that a sequence of horizontal fractures forms from the top down, and the resulting blocks are lifted off and ejected. The blocks can suffer secondary internal fractures. This experiment provides...
