Abstract:The Euler-Lagrange coupled method in AUTODYN was used to simulate
   concrete gravity dams subject to underwater contact explosion. The
   characteristics of damage crack distribution and dynamic responses of
   the gravity dam subjected to explosion loading from different explosion
   positions were analyzed. Considering the above characteristics, the
   aluminum foam was adopted as the antiknock material. Research results
   show that aluminum foam can effectively reduce the amplitude of shock
   wave and the dynamic response of the dam; meanwhile, the explosion
   damage on the dam was decreased and the scope of the cracks distribution
   was narrowed down. This shows the aluminum foam has good antiknock
   performance when used in underwater contact explosion.
