The Numerical Simulation about Exploding Load Attenuated by Foam Aluminum-Steel Sandwich Plate based on Mechanics of Explosion

摘要

Along with development of weapon technology, shock wave becomes a kind of instrument to kill people in blindage. It becomes more important to defend the damage of the shock wave. Through numerical simulation, the result is given. Foam Aluminum-steel sandwich plate can attenuate peak value of the shock wave. After shock wave overpass the sandwich plate that has foam Aluminum plate ten millimeters high, in an air layer, super pressure of shock wave drop to less than 0.05 atm., and the peak value of cracking pressure reduces 88 percent. So, people behind sandwich plate are fastened.
