Maximum principal stress in strike-slip faulting

Input(s)

$\sigma_{c}$: Least Principle Stress (psi)

$S_{\text {hmax }}$: Maximum Horizontal Stress (psi)

$P_{p}$: Pore Pressure $(\mathrm{psi})$

$S_{\text {hmin }}$: Minimum Horizontal Stress (psi)

Output(s)

б: Maximum Principle Stress (psi)

Formula(s)

$$ \sigma=\frac{\sigma_{\mathrm{c}} *\left(\mathrm{~S}_{\mathrm{hmax}}-\mathrm{P}_{\mathrm{p}}\right)}{\mathrm{S}_{\mathrm{hmin}}-\mathrm{P}_{\mathrm{p}}} $$
