Unconfined compressive strength of rock

Input(s)

\(S_{o}\): Cohesive Strength (psi)

\(\mu\): Slope of Failure Line (dimensionless)

Output(s)

\(C_{o}\): Unconfined Compressive Strength of Rock (psi)

Formula(s)

\[ C_{\mathrm{o}}=2 * S_{\mathrm{o}} *\left(\left(\mu^{2}+1\right)^{0.5}+\mu\right) \]
