WebShock waves rapidly densify a powder with modest heating and high stresses [95]. If the material is brittle, then preheating is required prior to compaction. Densification is rapid by plastic flow while the material thermally softens from frictional self-heating. An example layout for explosive consolidation is given in Figure 10.42.

WebSep 9, 2024 · $\begingroup$ a shock wave occurs in air anytime the local flow velocity exceeds the speed of sound. since parcels of air must accelerate as they flow over the top of a wing, there will come a point where the flow over the top of the wing goes supersonic even though the flow over the rest of the wing is not. $\endgroup$ green board with standWebApr 9, 2024 · For even higher flight speeds, a detached shockwave appears in front of the airfoil: the purpose of this wave is to "turn" the flow around the airfoil.
