where [V.sub.PR] = ([V.sub.11] + [V.sub.22] + [V.sub.33])/3 is the mean value of compression wave velocity in the anisotropic sample.
Figure 1 shows the custom water-filled, temperature-controlled chamber used for in vitro exposure to high-rate compression wave which mimics a shock wave profile.
The full model predicts finite-velocity propagation of compression wave; however, behind the wave front the pressure distribution practically coincides with that given by (18).
The speed of the wave propagation was shown in the order of tens of meters per second, much less than the speed of a compression wave in water.
The hypersonic flow field of Region A3 is significantly changed by the compression and expansion waves induced by the distributed roughness, especially the first compression wave and the last two expansion-compression waves.
When a cylindrical explosive is detonated in the blasting hole, the explosion stress wave propagates outwards in the form of compression wave. The adjacent empty hole wall can be considered as a free surface due to no constraints.
The phasing of this compression wave was not changed with the backpressure, which was around 530[degrees]CA in all the cases.
When the first compression wave reaches the metal plate, the boundary conditions are
Resuming the results presented above, we can state that the compression wave, whose shape is initially continuous and smooth enough, propagates with a constant speed [V.sub.f] = [c.sub.s] until the shock pulse is formed.
It uses a compression wave spring to apply constant downward pressure, enabling the device to interconnect to the target PCB.
The socket uses a compression wave spring to apply constant downward pressure enabling the device to be interconnected to the target PCB.
The very strong compression wave transducers were installed on the top and bottom of the specimen.
