我们进行了穿透深度实验与卵形头弹丸和混凝土目标的无侧限抗压强度标称为14 MPa（2千磅/平方英寸），35 MPa（5千磅/平方英寸），和97 MPa（14千磅/平方英寸）。根据我们的数据和坎菲尔德和Clator [J. A.坎菲尔德和我。G. CLATOR，研究混凝土中渗透的比例律和技术的发展。NWL报告第2057号，美国海军武器实验室，Dahlgren，VA（1966）] [1]，我们开发了一个经验公式，在正常的影响下，卵形头弹侵彻混凝土目标的侵彻深度。我们的渗透方程包含一个单一的，无量纲的经验常数，只取决于无侧限抗压强度的目标。我们确定的经验常数从穿透深度与撞击速度数据与六组穿透数据之间的撞击速度250和800米/秒。预测结果与所有六个数据集吻合良好。
We conducted depth of penetration experiments with ogive-nose projectiles and concrete targets with unconfined compressive strengths of nominally 14 MPa (2 ksi), 35 MPa (5 ksi), and 97 MPa (14 ksi). From our data and the data presented by Canfield and Clator [J. A. CANFIELD and I. G. CLATOR, Development of a scaling law and techniques to investigate penetration in concrete. NWL Report No. 2057, U.S. Naval Weapons Laboratory, Dahlgren, VA (1966)] [1], we developed an empirical equation for penetration depth of ogive-nose projectiles penetrating concrete targets at normal impact. Our penetration equation contains a single, dimensionless empirical constant that depends only on the unconfined compressive strength of the target. We determine the empirical constant from penetration depth versus striking velocity data with six sets of penetration data for striking velocities between 250 and 800 m/s. Predictions are in good agreement with all six data sets.
