The Mohr-Coulomb Failure Criterion represents the linear envelope that is obtained from a plot of the shear strength of a material versus the applied normal stress.  This relation is expressed: `tau=sigmatanphi+c`, where:

  • `sigma` = normal stress
  • `phi` = slope of the failure envelope
  • `c` = intercept of the failure envelope (cohesion)
