【 摘 要 】

To evaluate the suitability of three typical concrete material models, which are HJC material model, RHT material model and K&C material model respectively, in simulating concrete's dynamic damage under air blast, a comparison between experiment observations and numerical simulation results is conducted. The three typical concrete material models are reviewed briefly at first. Then the experiment and numerical model information are presented. According to the comparison results, K&C material model shows the best suitability in simulating the damage mode of the concrete slab. RHT material model takes the second place for underestimating the concrete's strength resistance. HJC material model, however, is no recommended for simulating concrete in such a situation.
