四十多年前，阿列克谢耶夫斯基（Alekseevskii）和塔特（Tate）独立建立了修正的长杆侵彻半无限目标的流体力学理论，此后许多研究者对高速侵彻力学的发展做出了重要贡献。然而，在目前提出的所有模型中，目标电阻没有很好地定义，通常通过调整它来确定，直到预测的穿透深度与实验数据一致。本文首先对颗粒速度和压力分布以及靶内的响应区域进行了假设，然后对修正的长杆侵彻半无限靶的流体力学理论进行了推广，其中hrh具有明确的形式，并与侵彻速度和靶材料的热力学性能有关。将该模型与不同材料组合下的长杆侵彻试验进行了比较。虽然文中引入了许多假设和简化，但模型在侵彻深度方面的预测结果与实验数据和数值模拟结果基本一致。
The modified hydrodynamic theory of long rod penetration into semi-infinite targets was established independently by Alekseevskii and Tate over forty years ago and since then many investigators contributed much to the development of the high speed penetration mechanics. However, in all the models proposed so far, the target resistanceRtis not well defined and usually determined by adjusting it until the predicted depth of penetration comes to an agreement with experimental data. In this paper, assumptions are first made about particle velocity and pressure profiles together with response regions in the target and then an extension is made to the modified hydrodynamic theory of long rod penetration into semi-infinite targets, in whichRthas explicit form and is dependent on penetration velocity as well as thermo-mechanical properties of target material. The present model is compared with long rod penetration tests for different material combinations. It transpires that the present model predictions are in good agreement with the experimental data and numerical simulations in terms of penetration depth although many assumptions and simplifications are introduced into the paper.
