Yield strength (Bingham plastic model)
Input(s)
\(\mathrm{K}\): Bulk Modulus (psi)
G: Shear Modulus (psi)
\(\rho\): Density \((\mathrm{ppg})\)
Output(s)
\(V_{p}\): Velocity of Compressional Waves \((\mathrm{ft} / \mathrm{s})\)
\(V_{s}\): Shear Waves \((\mathrm{ft} / \mathrm{s})\)
Formula(s)
\[
\begin{gathered}
\mathrm{V}_{\mathrm{p}}=\left(\frac{\mathrm{K}+\frac{4 * \mathrm{G}}{3}}{\rho}\right)^{0.5} \\
\mathrm{~V}_{\mathrm{s}}=\left(\frac{\mathrm{G}}{\rho}\right)^{0.5}
\end{gathered}
\]
