...B. Simoens; M. H. Lefebvre; R. E. Nickell; F. Minami; J. K. Asahina Detonation chambers (either mobile or fixed) are used worldwide for a wide range of applications. At present, a 1/7 scale model of a 1 ton detonation chamber is available for extended testing in Belgium. The chamber is a single...

... to catastrophic detonation of the entire charge. The degree of violence depends on many variables, including the rate of energy delivery, the physical and chemical properties of the explosive, and the strength of the confinement surrounding the explosive charge. The current state of experimental and computer...

...Toru Hamada; Yuichi Nakamura; Shigeru Itoh The detonation pressure from the steady detonation of high explosives is a characteristic. Nevertheless, in materials processing using high explosives, there are cases when the detonation pressure does not match the intended pressure. In this investigation...

... (1) statically loaded with oil, (2) statically loaded with nitrogen, and (3) dynamically loaded with gaseous detonations traveling at 2.4 km/s. The tubes were also instrumented with pressure transducers, crack detection gages, and strain gages. The experiments were controlled so that comparisons...

... by adequately changing the form of the explosion of high explosive. Starting from this motivation, we put forward a new method for producing high dynamic pressure from the use of the overdriven detonation of high explosive. The proposed device consists of the following configurations. A metal flyer accelerated...

... to the relation of propagation velocity of underwater shock wave, detonation velocity of the explosive and a configuration of vessel to charge the explosive. In order to study an effect of the convergence, pressure measurement at the spiral center was carried out by using a manganin gauge. Therefore, when SEP...

...G. O. Thomas Pipes with nominal diameters 300 mm constructed from GRP or medium density polyethylene (MDPE) have been subject to transient internal pressure loads, generated by ethylene-air detonations. Several GRP sections survived repeated tests, while an MDPE pipe failed in a catastrophic manner...
