Abstract：The damage model of brittle materials under impact load is very important for study of blast，penetration，and collision with high velocity. However，there are many difficulties in such study，which come from two aspects as follows：(1) the complexity of response of brittle materials under impact load；and (2) the difficulty to carry on simulating test and measuring method. Therefore，the research situation and methods of damage model for brittle materials under impact load have been summarized since recent 20 years，and the tendency and existed problems have also been discussed. The variables of damage model directly determine the level (macro-，meso-，and microcosmic level) and the basic method. Accordingly，the current damage models that describe the mechanical response of brittle materials under impact load are classified according to different damage variables，and the developing tendency are also commented.
