divided up equally, you can see that lighter objects will have higher velocities, as you
might expect. You can also adjust the amount of explosion energy available to each
object by weighting the object's imparted energy by its distance from the explosion. This
should also be tuned in the program, but in general, pressure from an explosion de‐
creases with the cube of distance and exponentially with time.
If you want to model more complex explosion-structure interactions, there are many
good references for how, say, buildings, react to bomb blasts. FEMA, as well as the Army
and Navy, have several papers on the subject, such as FEMA 426 Reference Manual to
Mitigate Potential Terrorist Attacks Against Buildings . The general concepts laid out in
such documents can increase the realism of the building damage due to explosions.
