the testing is to determine the uniaxial compressive strength and the elastic
properties, represented by Young’s modulus and the Poisson ratio, of cylindrical specimens of
intact rock sampled from drill cores. Moreover, the specimens had a water content corresponding
to the in-situ conditions. The loading was carried out into the post-failure regime in order to
study the mechanical behaviour of the rock after cracking, thereby enabling determination of the
brittleness and residual strength.
