Deformation and strength anisotropy of Asan gneiss, Boryeong shale, and Yeoncheon schist

► Results of deformability and strength anisotropy on three rock types found in Korea are reported. ► The experiments were conducted on rock specimen obtained from the directional coring system. ► The anisotropy ratios of elastic modulus were from 1.7 to 4.0 for rock types in this study. ► The applicability of transversely isotropic model was quantitatively investigated.
