Uniaxial Compressive Behavior of Granite at High Strain ...

2021-6-20  To obtain the uniaxial compressive strength of the granite, an MTS-793 fatigue machine (Fig. 2a) was employed with a displacement-control mode at a loading rate of 0.3125 μm/s. With this machine, the static fracture behavior could be fully demonstrated (Fairhurst and Hudson 1999; Zang and Wanger 2000).The standard cylinders (Fig. 2b) were placed on the

2015-6-4  Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or
