英文摘要	An algorithm based on the basic principles of continuum media mechanics and the primary idea of the DEM were developed for calculating the dynamic damage process of brittle media. The wave propagation in an orthotropic plane under impact loadings was numerically simulated by using this algorithm. Comparing its results with those by LS-DYNA, the accuracy of this algorithm was presented. The failure process of a steel bullet penetrating a concrete circular plane was demonstrated, which presented the dynamic transitional process from continuum media to non-continuum media. Several different fundamental damage forms simulated by using this algorithm were discussed, and the calculation results with this algorithm were compared with the results of penetration experiments. The two numerical examples prove that this algorithm is powerful and efficient for simulating the dynamic failure problems accompanied with the transition from continuum media to noncontinuum media.; EI; 0; 2; 127-132; 20
