elastic wave การใช้

• Setting the first term equal to zero yields the elastic wave equation.
• Geophysical surveys show the seismology data of elastic waves, mainly seismic reflection.
• Recently, such light-pressure-induced elastic waves were observed inside an ultrahigh-reflectivity dielectric mirror.
• Thermal energy in solids is often carried by internal elastic waves, called phonons.
• Elastic waves are sound waves generated for the purpose of going through solid objects.
• Elastic waves of different lengths, frequencies, and amplitudes run through crystalline solids at all times.
• Elastic waves define a spectrum between ultraviolet and light.
• Elastic waves are used to probe the site under investigation, by placing seismic vibrators on the ground surface.
• In general, elastic waves in solid materials are guided by the boundaries of the media in which they propagate.
• Its projected applications, with a future expanded frequency range in elastic wave systems, are seismic wave reflection and ultrasonics.
• 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.
• In the case of the earth's inner core, the directional differences of elastic waves are seen as offering solid clues to its composition.
• The elastic wave equation in three dimensions describes the propagation of waves in an isotropic ultrasonic waves used to detect flaws in materials.
• 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.
• 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.
• 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.
• 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.
• 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.
