Maximum principal stress in reverse faulting

Input(s)

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

PpP_{p}: Pore Pressure (psi)

SvS_{v}: Vertical Stress (psi)

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

Output(s)

б: Maximum Principle Stress (psi)

Formula(s)

σ=σc( ShmaxPp)SvPp\sigma=\frac{\sigma_{\mathrm{c}} *\left(\mathrm{~S}_{\mathrm{hmax}}-\mathrm{P}_{\mathrm{p}}\right)}{\mathrm{S}_{\mathrm{v}}-\mathrm{P}_{\mathrm{p}}}
