where p, I, td are peak pressure, +ve impulse and duration, respectively measured at R from W
kg of explosive and f, F, Ø are unspecified functions. Cube root scaling has been verified by
experiment but does not describe the decay of peak pressure with distance.
(3) Application of scaling laws
In practice scaling laws are used:
1. to obtain shock parameters for any size of explosive charge from those of a standard of the
explosive;
2 to produce a standard charge using experimental methods.
Example 1:
Cube root scaling indicates that if a similar charge of mass M2 has a diameter d2=kd 1
then p occurs at R =kR ; that is:
2

1
