Abstract: Overpressure absorbing material is positioned on the exterior of an enclosure. When an explosion occurs adjacent the enclosure, the overpressure absorbing material absorbs a large portion of an incoming overpressure wave from the explosion.

The overpressure wave from the explosion may enter the enclosure via a breach or other opening and may resonate within the enclosure, causing injury to the enclosure's occupants. The interior overpressure absorbing material also prevents a significant magnitude of the overpressure wave from being reflected off the interior walls of the enclosure, resonating within the enclosure, and causing injury to the enclosure's occupants.
