NettetA linear, transversely isotropic, elastic half-space is excited by a buried point source. The stress-free surface of the half-space is normal to the axis of material symmetry. By means of integral transforms, an explicit solution is obtained at the epicenter for hexagonal–crystals whose Cagniard inversion path requires contour integration. … In isotropic media, the stiffness tensor gives the relationship between the stresses (resulting internal stresses) and the strains (resulting deformations). For an isotropic medium, the stiffness tensor has no preferred direction: an applied force will give the same displacements (relative to the direction of the force) no matter the direction in which the force is applied. In the isotropic case, the stiffness tensor may be written: http://ta.twi.tudelft.nl/Ftp/TWA_Reports/00/00-09bnew.pdf my go easy stib
