Shock Factor

Shock factor is a commonly used figure of merit for estimating the amount of shock experienced by a naval target from an underwater explosion as a function of explosive charge weight, slant range, and depression angle (between vessel and charge).
$SF\; =\; \{\backslash frac\{\backslash sqrt\; W\}\{R\}\}\; \{\{(1+\backslash sin\; \backslash phi)\}\; \backslash over\; 2\}$
The application scenario for Equation 1 is illustrated by Figure 1.
The numeric result from computing the shock factor has no physical meaning, but it does provide a value... meer
