Dynamic pressure impulse, I sub q was evaluated as a function of wheeled vehicle displacement 14 ton and 2-12 ton trucks for idealnear ideal and nonideal blast environments. Good correlation was obtained between dynamic pressure impulse and vehicle displacements using least squares fits. Using the quadratic equations derived by least squares fit the I sub q were calculated from known vehicle displacements and these were averaged with initial estimates of I sub q idealnear-ideal and measured I sub q non-ideal to obtain iterated values of I sub q. Least square fits were also applied to I sub q versus scaled ground range and displacement versus scaled ground range for various values of n, the exponent of yield. The values of n providing the best fits were between 0.4 and 0.43 for displacements and n 0.42 or 0.43 for I sub q as a function of scaled range.
