Validation and application of empirical shear wave velocity models based on standard penetration test
Shear wave velocity is a basic engineering tool required to define dynamic properties of soils. In many instances it may be preferable to determine Vs indirectly by common in-situ tests, such as the Standard Penetration Test. Many empirical correlations based on the Standard Penetration Test are broadly classified as regression techniques. However, no rigorous procedure has been published for c...
متن کاملObservation of nonlinear shear wave propagation using magnetic resonance elastography.
MR elastography (MRE) is an MRI modality that is increasingly being used to image tissue elasticity throughout the body. One MRE technique that has received a great deal of attention is based on visualizing shear waves, which reveal stiffness by virtue of their local wavelength. However, the shape of propagating shear waves can also provide valuable information about the nonlinear stress-strain...
متن کاملimportance of mode detection in ambient noise array application for shear wave velocity profile determination
in this paper we are going to show the importance of mode identification in microtremor array analysis. the idea come from four concentric ambient noise array recordings with aperture 100 to 1000 meters, performed in southern urban area of tehran near the shrine of imam khomeini. these measurements were part of a comprehensive research project with the aim of determination of deep shear wave ve...
متن کاملAnalysis of Wave Propagation in 1D Inhomogeneous Media
In this paper we consider the one dimensional inhomogeneous wave equation with particular focus on its spectral asymptotic properties and its numerical resolution. In a first part of the paper we analyze the asymptotic nodal point distribution of high frequency eigenfunctions, which, in turn gives further information about the asymptotic behavior of eigenvalues and eigenfunctions. We then turn ...
