The absorbing structures for high rate energy like explosions and intense impacts due to high damage itcauses and such disaster happens are widely investigated by researchers. Ass the main destruction factor ofan explosion, shockwave can cause a lot of damage. Understanding the mechanical properties of theshockwave and how much energy is released from a blast can build an absorbing structure for improvingthe safety of vehicles and occupants. The most effective shockwave energy absorption structures have beeninvestigated. The experimental procedure of previous studies considering financial resources has beenreviewed and concluded that materials for use in shockwave energy-absorbing designs are vast. It can getdifferent absorption structures according to what application these absorbing panels are used and due to thehigh cost of explosion experiments and modeling shock waves, finding shock tube experiments is financial.In the recent decade, foam-filled multi-layer panels have been used widely. Sandwich panels can be usedfor more flexible applications due to their lower density; however, it is evident that using multi-layer panelsin vehicle body structure usually leads to a heavy fuselage and limited mobility. All these measures are takenfor a time when the intensity of the explosion is not high; for this reason, complete protection of vehiclesagainst explosions is not possible due to the indefinable type of threats.
