... Abstract Two filtration components installed on a developmental aircraft cracked during pressure impulse testing. Both parts were made from an aluminum alloy, solutionized and aged, and cracked due to fatigue. In both cases, the crack initiated at a transition region on an inner surface...

... continuously and uniformly to every part of the fluid and to the surfaces of its container. Instead, a pressure impulse propagates throughout the fluid. If the propagation velocity is higher than the specific sonic speed in the medium, the pressure impulse is called a shock wave. As soon as this wave strikes...

...). This corresponds to an abrupt, impulsive impact of the indenter on the test material. The indenter can thus be shot like a bullet to the target surface, or the indenter can already rest on the surface before the force is abruptly applied from the outside, for example, by a hammer. It is important that the kinetic...

.... A new weldability test, called an impulse decanting test, is shown in Fig. 13 . This test utilizes a high-pressure jet of argon gas that is impulse-released through the bottom of a modified GTAW torch to decant, or expel, the liquid weld pool. A control box contains the necessary timing circuitry...

... are described in later sections. Explosive chemicals under suitable impulse undergo decomposition at a very fast rate. This liberates a large amount of energy with the evolution of a large volume of gas at very high pressure and temperature. Particle velocities during explosion can be as high as 8000 m per...

.... Of these, explosion welding is the most “exotic” form of pressure welding; controlled detonation is used to force metal workpieces together under a rapid impulse. During this event, air between the parts is expelled in the form of a supersonic jet, which strips away surface oxides and causes localized heating...
