Analytical solutions of axial, lateral, circumferential and volumetric strains, and post-peak Poisson'sratioofrock specimen subjected to shear failure in uniaxial compression are proposed.
This paper proposes that Poisson'sratioofrock mass and in-situ stress are directly determined using optimization method according to measured strains obtained from bore hole stress relief process.
