Shear wave velocity-based evaluation of liquefaction resistance of in-situ sand with aging effects
Yantu gongcheng xuebao, 2023 The shear wave velocity is one of the commonly used parameters to evaluate liquefaction resistance of sandy soils. In this study, based on the initial liquefaction criterion-based shear wave velocity characterization model (i.e., the "Zhou-Chen model ...

Cardiac Shear Wave Velocity Detection in the Porcine Heart [PDF]
Ultrasound in Medicine & Biology, 2017 Cardiac muscle stiffness can potentially be estimated non-invasively with shear wave elastography. Shear waves are present on the septal wall after mitral and aortic valve closure, thus providing an opportunity to assess stiffness in early systole and early diastole.

Effects of Particle Shape on the Shear Wave Velocity and Shear Modulus of 3D Printed Sand Analogs
Open Geomechanics, 2022 Isolating the effects of individual particle properties (e.g. shape, size, mineralogy, surface roughness) on the mechanical behavior of naturally occurring coarse-grained soils is a significant challenge in experimental studies.

Inner core composition paradox revealed by sound velocities of Fe and Fe-Si alloy
Nature Communications, 2022 The origin of the observed low shear wave velocity in the solid inner core is unclear. Here, the authors report shear wave velocities of iron and iron-silicon alloy under Earth’s core conditions by shock compression and find that neither the effect of ...
