Breast shear wave velocity ratio
WebThe shear modulus is related to shear wave velocity as 2 max = ρG V s [3] where Gmax is small-strain shear modulus in Pa, ρ is the soil density in kg/m3, and V s is the shear wave velocity in m/s. The compression wave (P-wave) velocity, Vp, can be derived from the S-wave velocity (Vs) and the Poisson’s ratio (ν) as ν ν 1 2 2(1 ) − − ...
