- 摘要: 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. - 备注: 新增回溯数据
