... of elastic parameters of transversely isotropic rocks is classically carried out by performing uniaxial or triaxial tests on small rock cylinders with different orientations of the plane of isotropy. A possible alternative is biaxial testing of large hollow rock cylinders. This technique has been applied...

...° radius in a transversely isotropic S° medium with an arbitrary directed plane of isotropy (in which the Ox axis inclined by the ß angle to the Ox' horizontal one is located), simulating the naturally anisotropic solid rock or the rock weakened by a double - periodic chink set. In the latter case...
