shear wave การใช้

• Shear wave splitting measurements have been used successfully to predict several earthquakes.
• Thus, a simple liquid will not typically support a transverse acoustic phonon, or shear wave.
• The shear waves are generated by an electro-mechanical transducer on the surface of the skin.
• Crampin ( 1980 ) proposed the theory of earthquake prediction using shear wave splitting measurements.
• The speed of shear waves is determined only by the solid material's shear modulus and density.
• These methods use different means to generate and measure the propagation of shear waves in tissue.
• The shear wave evanescently decays into the liquid.
• This allows shear or quasi-shear waves to be generated with a large amplitude in the through-thickness direction.
• In addition, the motion amplitude decays and the longitudinal and shear waves, that travel in the bulk.
• They confirmed the development of SH long-crested BL oscillations, the dynamic shear waves of transition to turbulence.
• Damage due to shear waves extends to even greater distances in abdominal injuries in the WDMET data.
• The wave is generated by horizontally striking an object on the ground surface to induce the shear wave.
• In seismology longitudinal and shear waves are known as P-waves and S-waves, respectively, and are termed body waves.
• Since the shear wave is the second fastest wave, it is sometimes referred to as the secondary wave.
• This encodes the amplitude of the shear wave in the tissue in the phase of the MRI image.
• It is followed by the more energetic but slower-moving S or shear wave that causes far more violent shaking.
• The two types of seismic body waves are compressional waves ( P-waves ) and shear waves ( S-waves ).
• "Use of refraction microtremor ( ReMi ) data for shear wave velocity determination at an urban bridge rehabilitation site"
• S-wave refraction evaluates the shear wave generated by the seismic source located at a known distance from the array.
• Hence, shear waves naturally " split " into separate arrivals with these two polarizations; in optics this is called birefringence.
