Nonlinear response of concrete beams and plates under impact loading

The paper presents a three-dimensional nonlinear finite element analysis of reinforced concrete targets under impact loading. The reinforced concrete has been modeled with strain rate sensitive elasto visco-plastic two surface model. The model is capable of predicting cracking of concrete and yielding of steel. Experiments were conducted in the laboratory involving drop hammer loading on circular concrete plates, these have been presented and analysed. The results show good agreement with our experiments and with some other experiments taken from literature.
