Evaluation of rock brittleness based on completestress-strain curve

HIGHLIGHTS

  • who: Liqi Xu et al. from the School of Transportation and Civil Engineering, Nantong University, Nantong, China have published the research: Evaluation of Rock Brittleness Based on CompleteStress-Strain Curve, in the Journal: Mathematics 2022, 10, 4470. of /2022/
  • what: In this paper, from the point of view of the complete stress-strain curve of rock, the commonly used and the latest brittle evaluation indexes are analyzed. The study shows that the smaller the total strain of the rock before stress damage, the steeper the straight-line section before the peak, the larger the post . . .
