Numerical Simulation of Shock Response and Dynamic Fracture of a Concrete Dam Subjected to Impact Load

The shock response and dynamic fracture of concrete gravity dams under impact load are the key problems to evaluate the antiknock safety of the dam. This study aims at understanding the effects of impact shock on the elastic response and dynamic fracture of concrete gravity dams. Firstly, this paper...
