Numerical Simulation on Underwater Shock Wave Focusing

Applied Mechanics and Materials, 2011
Shock wave focusing by an ellipsoidal reflector can produce higher pressure in the focal region. The focusing process of shock wave was studied by theory analyses and numerical results. Base on the experimental observation the shock wave source is equivalent to the explosion of an underwater explosive.

Evolution characteristics of shock waves in the muzzle flow field of an underwater gun in series launch

The Physics of Fluids
The muzzle flow field of underwater guns involves the interaction and reflection of shock waves within the propellant gas jet. When underwater guns are fired in series, the evolution of the shock wave structure in the muzzle flow field becomes more ...

Underwater shock consolidation of Mg–SiC composites

Journal of Materials Science, 2010
The shock consolidation of magnesium (Mg)/silicon carbide (SiC) composites using axisymmetric explosive fabrication setup is reported. Pure Mg and SiC powders are consolidated in a three-layered cylindrical assembly with the energy being derived from a high-detonation velocity explosive.

Ship Shock Modeling of Underwater Explosion

Solid State Phenomena, 2011
Ship shock tests have been conducted for shock qualification of hull integrity and proper operation systems and subsystems. The ship shock trial identifies design and construction and it also validates shock hardening criteria. The main problem is that ship shock trials are costly.

ROCKET MOTOR DESIGN FOR UNDERWATER SHOCK

Naval Engineers Journal, 1988
ABSTRACTNaval ships and equipment are designed to survive underwater shock. The underwater shock can result from a nearby explosion of a bomb or missile, or the underwater detonation of a nuclear weapon. The shock wave travels through the water and applies an impulsive pressure load to the ship. The ship responds by a sudden acceleration in a direction

Metal Pipe Forming Using Underwater Shock Wave

Emerging Technologies in Fluids, Structures and Fluid Structure Interactions: Volume 1, Fluid Dynamics, Fluid Structure Interaction, and High Explosive Detonation, 2002
Recently, many metal pipes have been manufactured and used as various mechanical parts. Cross section of these parts has circular and oval shape. And then, a lot of kinds, but a small quantity production of these metal pipe increases. However, commonly, very expensive metal die are used in that case.

Laser-induced plasma shock wave propagation underwater

Optik, 2013
Abstract By means of a high-sensitive optical beam deflection technique (OBD), the evolution of laser-induced plasma shock wave propagation in water is investigated in detail. The results provide the formation and development of laser-induced plasma shock waves.
