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.

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.

Explosive Strength Deficit as a Predictor of Vertical Jumping Performance

The Journal of Strength and Conditioning Research, 2002
Currently, variables predictive of vertical jumping performance can account for only part of its total variability. A potential additional source of variation called explosive strength deficit (ESD) was described in 1995 by Zatsiorsky (Science and Practice of Strength Training. Champaign, IL: Human Kinetics, 1995. pp. 34-35.).

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).

Effects of Self-Selected Music on Strength, Explosiveness, and Mood

Journal of Strength and Conditioning Research, 2012
There has been much investigation into the use of music as an ergogenic aid to facilitate physical performance. However, previous studies have primarily focused on predetermined music and aerobic exercise. The purpose of this study was to investigate the effects of self-selected music (SSM) vs.

Signal strength of marine seismograph explosives

Geophysics, 1967
Abstract 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.

Mixed Maximal and Explosive Strength Training in Recreational Endurance Runners

Journal of Strength and Conditioning Research, 2014
Supervised periodized mixed maximal and explosive strength training added to endurance training in recreational endurance runners was examined during an 8-week intervention preceded by an 8-week preparatory strength training period. Thirty-four subjects (21-45 years) were divided into experimental groups: men (M, n = 9), women (W, n = 9), and control ...

Initiation of Explosives by Low Strength Shocks

1974
Abstract : This report describes a study of initiative processes involving weak (i.e. kbar strength) shocks. In the period covered by this contract the authors have done work on the drop-weight impact test, micro-particle initiation of explosives, multiple shocking of samples of PETN and have used mass-spectrometry for decomposition studies of PETN ...

COMPRESSIVE STRENGTH AND EXPLOSIVE CHARACTERISTICS OF POLYMER-BONDED EXPLOSIVES BASED ON HEXOGEN AND FLUOROELASTOMERS

Journal of Military Science and Technology, 2020
This paper describes the formulation of two polymer-bonded explosives based on RDX (hexahydro-1,3,5- trinitro-1,3,5-triazine) and fluoroelastomer binders by the water-slurry coating method. The fluoroelastomers are poly(VDF-HFP) (vinylidene fluoride-hexafluoropropene copolymer) and poly(VDF-CTFE) (vinylidene fluoride-chlorotrifluoroethylene copolymer).

Strength effects in explosively-imploded cylinders

2014
The dynamic implosion of five thin-walled metal cylinders of different strengths (aluminum 6061-O, aluminum 6061-T6, steel 1018, and stainless steel 304) was studied experimentally at two constant mass-to-explosive (M/C) ratios. The velocity history of the inner surface of the imploding cylinder was recorded via photonic Doppler velocimetry (PDV).
