岩石类介质侵彻效应的理论研究进展

Review on theoretical research of penetration effects into rock-like material

近年来,随着超高速武器的发展,侵彻效应的研究重点逐渐由高速向超高速发展。随着弹体打击速度提高,侵彻机制发生变化,并触发强烈的成坑和地冲击效应。本文综述了大速度范围内岩石类介质侵彻效应的理论研究进展,讨论了长杆弹侵彻速度的分区,介绍了岩石类介质的侵彻、成坑、地冲击效应的理论模型,并对目前研究中尚有待解决的问题和下一步的研究方向进行了展望。

In recent years, as the developing of hyper-velocity weapons, the research emphasis of penetration effects is shifting from high-velocity penetration to hyper-velocity penetration. With the increasing of impact velocity of projectiles, the penetration mechanism changes, where effects as cratering and ground shock are induced. In this paper, progress in theoretical research of penetration into rock-like materials in a wide velocity range is reviewed, where velocity range is divided into zones, and theoretical models of penetration, cratering and ground shock are introduced. The existing problems concerned and research orientation in the future are also forecasted.
