【摘要】 本文对目前常用的弹丸侵彻混凝土深度的经验公式进行了分析比较,通过分析其表达式,得出了在运用经验公式时应注意的问题以及应用范围等,对影响侵彻深度的因素做了初步分析。分析表明,现有经验模型的不完备性和现有设计和评估准则的局限性,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、理论和数值模拟等研究工作,以便在侵彻问题上找到一个更为完善的经验公式。更多还原

【Abstract】 The empirical formulas for projectiles penetration into concrete are compared and analyzed.According to analysis, it is shown that there are some problems and limit domain in the penetration depth calculation.The influence factors are also analyzed.It is make clear that the existing empirical models are not sufficient and the design and evaluation rules are not maturity.So further work for improving the computational codes,such as experiment,theory,simulation research should be supported.The aim is to find a more perfect empirical equation.更多还原
