Can you explain in details on why the angle between the normal stress (x-axis) and the plane of failure doubles in Mohr-Coulomb Failure criteria space and still the same in real world stress space?

  • $\begingroup$ what angles? Please edit your question. $\endgroup$ – Jan Doggen Aug 23 at 7:23
  • $\begingroup$ Hello dear @JanDoggen , the question is very clear, the angle (beta)between the normal stress (x-axis) and the failure plane becomes double(2 *beta) in mohr circle while still only ( beta) in real world space $\endgroup$ – aows61 Aug 23 at 7:50
  • $\begingroup$ This is possibly more of an engineering question than an earth science question. $\endgroup$ – Fred Aug 23 at 13:47
  • $\begingroup$ Hello @Fred it is part of structural geology $\endgroup$ – aows61 Aug 23 at 13:48
  • $\begingroup$ @aows61 if the question was very clear, I doubt that Jan Doggen woudl have asked for clarity. Your comment does, in fact, add useful new information. I recommend that you edit this into the question. $\endgroup$ – Semidiurnal Simon Aug 23 at 19:47
