Particles propagate in the spacetime continuum as longitudinal wave
In this case, the TT samples had a thickness along the axis of compression and the ultrasonic measurements provided the longitudinal wave
modulus along this axis, and the TA samples had a thickness along the direction perpendicular to the axis of compression and so the ultrasonic tests provided the longitudinal wave
modulus along the transverse direction.
The time distribution of the loading point force, applied at point A, is prescribed by the rectangular pulse, whose duration corresponds to time when the primary longitudinal wave
reaches half the length of the specimen.
The values of longitudinal wave
and shear wave velocities of fresh and weathered oil shale and rock samples, in both horizontal bedding orientation and vertical bedding direction, are given in Table 1.
During the tensile test the interdependency of the speed of surface ultrasonic longitudinal wave
propagation and stresses was identified, i.
The wave is composed of 1) a torsional wave and 2) a longitudinal wave
This is called a longitudinal wave
or a compression wave.
One practical devices utilizes longitudinal wave
propagation in rods is Hopkinson (or Davies) bar.
Even the Whittaker decomposition of electromagnetic fields is reinterpreted in terms of a longitudinal wave
in the time domain, possibly correlated with an emitted longitudinal electromagnetic wave in 3-space.
The agency said the power companies will use longitudinal wave
testing from now on, which should reduce the margin of error to 3 mm.
The longitudinal wave
can be visualized as hitting the bolt head with a hammer; it's a shock wave that travels the length of the bolt and yields a length indication.
The solution for the plane longitudinal wave
in a hexagonal lattice from  is extended by the case of weakly transverse variations.
