武器侵彻钢纤维混凝土深度的实用计算方法

The engineering method for calculating the depthof penetrating steel fiber concrete

武器对材料的侵彻过程同时也是材料损伤与能量耗散的过程,因而靶体材料韧性对武器侵彻深度有很大的影响,但是,现有经验公式均不能反映钢纤维混凝土材料韧性对侵彻深度的影响。对此,引入了钢纤维混凝土材料韧度η,并对计算效果较好的ACE公式进行了修正。修正后的公式不仅能反映材料韧性作用,而且在一定程度上也反映了武器侵彻过程中的材料损伤与能量耗散。同时,该公式适用于武器侵彻钢纤维混凝土深度的计算,并保持了原公式简单实用的特点,对相关工程与科研有一定的参考作用。

The material is damaged and the energy is dissipated while a projectile penetrates its target. Therefore, the toughness of target has profound influence on penetration depth. However, the toughness of steel fiber concrete was not considered in the available empirical formulae at present. In this paper, the ACE formula that has better result in calculating penetrating depth is modified by introducing the toughness index η. Not only the material toughness but also the material damage and energy dissipation are reflected by the new method. The new formula is simple as the ACE formula for practical use in penetration calculation, and can be used to determine the depth of penetrating Steel Fiber Concrete. It will have futher application to related scientific research and engineering.
