Strength of Commercial Explosives

Combustion, Explosion and Shock Waves, 2001
Strength is determined for mixtures of Amatol (79/21 AN/TNT) with various additives and mixtures of ammonium nitrate and aluminum of various compositions. The results obtained and literature data are used to obtain a formula for calculating the relative strength of commercial explosives containing two parameters — explosion heat and volume of explosion

Bond strength of explosively welded specimens

Materials & Design, 2008
Although the explosive welding process has been in commercial use since the mid-1950s it is to a large extent still empirical in nature, the effect of process variables on the final product is not fully understood and often the reasons for failure are unclear.

Kettlebell Swing Training Improves Maximal and Explosive Strength

Journal of Strength and Conditioning Research, 2012
The aim of this study was to establish the effect that kettlebell swing (KB) training had on measures of maximum (half squat-HS-1 repetition maximum [1RM]) and explosive (vertical jump height-VJH) strength. To put these effects into context, they were compared with the effects of jump squat power training (JS-known to improve 1RM and VJH).

Strength of Explosives. Trauzl Test

Combustion, Explosion and Shock Waves, 2004
A simple formula for calculating the absolute strength of an explosives as determined by the Trauzl test (expansion in a lead block) is proposed that contains only one parameter — the relative strength of the explosive calculated from the heat of explosion and the volume of explosion gases.

The seismic signal strength of chemical explosions

Bulletin of the Seismological Society of America, 1998
AbstractWe have compared the seismic magnitude of a wide variety of chemical explosions of known yield, to the magnitude expected for explosions set off in hard rock under conditions most favorable for generating strong seismic signals. Our results are based on numerous chemical explosions that include several different broad groups, mostly taken from ...

Strength of an Explosively-Formed Bond

2006
Abstract : A test fixture used to determine the shear strength of an explosively-formed bond between a liner and gun tube is described. Tests were carried out in which the liner material yielded before the bond was broken. A finite-element analysis of the deformation indicated that the bond shear strength was in excess of 45 ksi.

ELITE SOCCER'S LOWER LIMBS EXPLOSIVE STRENGTH ASYMMETRY

British Journal of Sports Medicine, 2013
BackgroundA vertical jump is one of essential motor skills in many sports (Vanezis & Lees, 2005). Monitoring and description of vertical jumps is based on both external movement structure and explosive strength of lower limbs as a basic driving impulse for its performance.

SIGNAL STRENGTH OF MARINE SEISMOGRAPH EXPLOSIVES

GEOPHYSICS, 1967
The impulse of the shock wave from an underwater explosion, as recorded under laboratory conditions, has been used to predict the signal strength of heterogeneous explosives of the nitro‐carbo‐nitrate type used in offshore seismic exploration. The changes in relative magnitude of the shock‐wave impulse due to changes in composition and to varying shot‐

Strength Testing of Explosives by Underwater Detonation

Propellants, Explosives, Pyrotechnics, 1978
AbstractShock wave energy and bubble energy for different explosives have been measured in underwater experiments. A method to determine bubble energies in cases where the free water surface and bottom boundary disturb the bubble oscillation has been developed.
