Observation of Shear-wave in Lambs Problem


Lamb (1904) proposed a numerical solution of transient waves for a point source and a point receiver located on the surface of elastic homogeneous half-space. After Lamb proposed his solution, some acoustical experimentalists tried to observe these transient waves. Longitudinal-, and Rayleigh-waves propagation along surfaces were measured, but the shearwave (S-wave) has never previously been observed until now.
