混凝土靶板冲击响应的经验公式

Empirical equations for the impact response of concrete targets

对预测混凝土靶板在弹丸撞击下的响应和破坏的经验公式进行了综述,包括预测侵彻深度、痂斑破坏和穿透的经验方程,并对国外现有的有关钢筋混凝土靶板抗弹设计和评估的规范进行了评论。结果表明,现有经验模型的不完备性和现有设计和评估准则的自身缺陷,清楚地说明有必要在混凝土撞击、侵彻和穿透这一活跃研究领域,做进一步的实验、理论和数值模拟工作,以便对余留问题找到令人满意的答案。

The development of empirical equations for the responses of reinforced concrete structures struck by missiles is reviewed. The existing codes for impact assessment and design of reinforced concrete targets are discussed. It is concluded that the existing empirical models are not sufficient and further work for improving the computational codes should be supported.
