In this paper a three dimensional finite element analysis of anisotropic brittle dynamic damage mechanism problem for arch dam and rock foundation subject to attack of a blast load has been carried out. The concept of damage strain energy release rate has been taken into account to develop the dynamic damage evolution model employed into the developed three dimensional anisotropic dynamic damage finite element program. The process of dynamic damage response in the dam due to attack of a blast load has been numerically simulated. The concepts of anisotropic brittle dynamic damage strain energy release rates ; 3D dynamic finite element analysis safety of arch dam under blast impact load are involved in studies of this paper. The developed analysis could provide a referenced basis on the computer simulation of brittle dynamic damage process in different structures.
