Velocity of bulk compressional waves

Input(s)

E: Young's Modulus (lbf/ft2)\left(\mathrm{lbf} / \mathrm{ft}^{2}\right)

ρ\rho: Density (lbm/ft3)\left(\mathrm{lbm} / \mathrm{ft}^{3}\right)

μ\mu: Poisson's Ratio (dimensionless)

Output(s)

VbV_{b}: Velocity of Bulk Compressional Waves (ft/s)(\mathrm{ft} / \mathrm{s})

Formula(s)

Vb=(Eρ1μ(1+μ)(12μ))0.5\mathrm{V}_{\mathrm{b}}=\left(\frac{\mathrm{E}}{\rho} * \frac{1-\mu}{(1+\mu) *(1-2 * \mu)}\right)^{0.5}
