| Abstract: | By experiments on Hopkinson pressure bar (SHPB), the dynamic mechanical behavior for four kinds of concrete as well as two kinds of fiber reinforced concrete are investigated. Based on the experimental data, a phenomenological analysis is made to study the influence of different ingredients on the uniaxial compressive strength of concrete under impact. The results can provide both theoretical and experimental reference for the concrete being used in engineering construction. |
