From: A new closed analytical solution for the elastodynamic half-space Green’s function
Comparison of imaginary part of the Green functions for the case of source and receivers at the surface of an elastic Poissonian half-space. The source is at the origin (0, 0, 0)T and the receivers are located along x-axis at (r, 0, 0)T, where r = horizontal distance. Results computed using EQP are depicted with discontinuous lines while the continuous lines correspond to DWN. Results display the non-dimensional Green’s function components \(\mu r \mathrm{Im}[{G}_{ij}]\) against the normalized distance \(r/\lambda_{\beta }\), where \({\lambda }_{\beta }=\beta /f\) = shear wavelength. The first two plots correspond Chao’s problem while the third one to Gi3 Lamb’s. Gray, yellow and blue lines represent motion in x, y and z directions, respectively
