Paper presented at the 55th U.S. Rock Mechanics/Geomechanics Symposium, June 18–25, 2021
Paper Number: ARMA-2021-1581
... of microscopic thermal cracking was investigated by SEM observation to reveal the temperature-dependent response of macro mechanical properties. Experimental results show that uniaxial compression strength, Young's modulus, and brittleness index slightly decreased with the increasing of number of cycles when...

... to be resting on a modified Hoek–Brown material. The material is assumed to exhibit perfect plasticity, obeying an associated flow rule. The effect of various parameters such as geological strength index (GSI), m for intact rock ( m i ), intact rock uniaxial compression strength ( σ ci ), and clear spacing...

Paper Number: ARMA-11-373
... ABSTRACT This paper intends to present the relation between uniaxial compression strength (UCS) and granitic samples’ geometry. In order to achieve this purpose, 92 samples from the same rock mass with 9 different geometric relations were tested for physical, mechanical and deformation...
