Linearized Mohr coulomb criteria
Input(s)
\(C_{o}\): Unconfined Compressive Strength of Rock (psi)
\(\mu\): Slope of Failure Line (dimensionless)
\(\sigma_{c}\): Minimum Effective Principal Stress (psi)
Output(s)
\(\sigma_{1}\): Maximum Effective Principal Stress (psi)
Formula(s)
\[
\sigma 1=\left(C_{o}\right)+\left(\left(\mu^{2}+1\right)^{0.5}+\mu\right)^{2} * \sigma_{c}
\]
