Investigation into the long-term strength of rocks under loading with a constant rate

  • V. P. Efimov


The test data are presented for tensile and compressive strength of some rocks depending on the rate of loading by three-point bending and then uniaxial rigid compression. The constants of Zhurkov’s kinetic equation of durability are determined for the tested rocks.
