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...
Strength and Conditioning Journal 13 in their training regimes (18, 25). It appears that explosive exercises tend to enhance an athlete’s ability to generate high rates of force development (18, 22, 25, 54), whereas slow exercises tend to impair this ability (24, 25, 50). Almost any exercise can be performed explosively depending upon the resistance used. Several studies and review articles hav...
The purpose of this study was to examine the effect of a short-term plyometric training program on explosive strength and endurance performance in highly competitive middle- and long-distance runners. Athletes were randomly assigned to a control group (CG, n = 18, 12 men) and an explosive strength training group (TG, n = 18, 10 men). Drop jump (DJ) from 20 (DJ20) and 40 cm (DJ40), countermoveme...
Die less explosive forming of circular plates is one of the most useful methods in the industries especially chemical applications. Manufacturing of large vessel's head, multilayer rings and some parts of heat exchangers are the example of applying this method. Many theoretical and experimental researches about examining the explosive forming of simple and single layer plate have been done. The...

The benefits of using insensitive high explosives (IHE) like PBX 9502 (9502) have been well documented [1]. These desirable features come at a price. The reaction zone is longer for IHEs, thus making them more nonideal. In real world applications, this translates into significant performance problems, such as problems with detonation wave spreading. The speed of detonation propagation is affect...
The improvised explosive device (IED), in all its forms, has become the most significant threat to troops operating in Afghanistan and Iraq. These devices range from rudimentary home made explosives to sophisticated weapon systems containing high-grade explosives. Within this broad definition they may be classified as roadside explosives and blast mines, explosive formed pojectile (EFP) devices...
