【Abstract】

<正>Concrete may be subjected to extreme dynamic loads such as blast loads and high velocity impact loads.Predicting the performance of concrete structures to explosive and impact loads through full-scale tests is often beyond affordability. With the rapid development of computer technology and the advancement of numerical techniques,it makes the predictions through numerical simulation viable.So far the most popular numerical simulation method is the wave propagation code,or hydrocode.In the numerical simulation,material model plays a vital role,which should be appropriate to reflect the concrete behaviour under highly dynamic loading.Many material models for dynamic concrete behaviour at high strain rates have been developed.Some of those models have been incorporated with hydrocodes.In the present paper,the typical concrete material models available in open literature are reviewed,their suitability is discussed.Our recent research results on numerical simulations with a simple dynamic damage material model are also presented.
