Features of Uniaxial Compression Failure of Brittle Rock Samples with Regard to Grain Characteristics

  • V. P. EfimovEmail author
Rock Failure


The results are presented for uniaxial compression testing of brittle rock samples; their failure occur in the form of columnar cracking along the axis of applying the force. Test results are compared with characteristic quantities determining tensile strength. Sample failure is modeled with regard for grain characteristics, which makes it possible to estimate the ratio of compression strength to tensile strength.
