The structure was found to be stable at the enormous pressures and to have directionality in the transmission of elastic waves.

In the early 1950s, Press turned to seismology, co-authoring with Ewing and Jardetzky a seminal monograph on elastic waves in layered media.
13.
In the case of the earth's inner core, the directional differences of elastic waves are seen as offering solid clues to its composition.
14.
The elastic wave equation in three dimensions describes the propagation of waves in an isotropic ultrasonic waves used to detect flaws in materials.
15.
Krylov predicted the existence of localised elastic waves in immersed solid wedges and proposed to use them for wave-like aquatic propulsion of marine vessels.
16.
One transducer is used to generate an elastic wave of constant amplitude and varying frequency, whereas the other is used to detect the sample's resonance.
17.
He joined Schlumberger Doll Research in Ridgefield, Connecticut in 1978, where he worked on applications of elastic waves in borehole vertical seismic profiling, and surface seismic.
18.
The reflection of a laser pulse from the surface of an elastic solid gives rise to various types of elastic waves that propagate inside the solid.
19.
In the case of the Earth's inner core, the directional differences of elastic waves were seen as suggesting that the mass of solid iron is actually a single giant crystal.

Where \ sigma is the impact stress, L is the length of the rod, c is the elastic wave speed, and h is the smaller lateral dimension of a rectangular rod.
