摘要

本文给出了圆柱高径比为1:1和5:1的薄圆柱靶动载荷的数值计算结果。为了确定棒状波在[001]、[011]和[111]方向上的传播速度，本文模拟了具有立方对称性质的VZhM8单晶镍合金的弹性波在不同高度与半径之比的圆柱体中的传播。采用三维有限元方法，对具有起始速度的钢弹对VZhM8靶体的装填问题进行了分析。

Propagation of longitudinal and rod waves in cylinders from polycrystalline and single-crystal materials under dynamic loading

The paper presents the results of numerical calculations of dynamic loading of thin cylindrical targets with a ratio of cylinder heights to its diameter 1 : 1 and 5 : 1. The propagation of elastic waves in cylinders with different ratios of heights to the radius of the VZhM8 single-crystal nickel alloy with cubic symmetry of properties in order to determine the propagation velocities of rod waves in the [001], [011] and [111] directions was simulated in this paper. The problem of loading of a target from VZhM8 by a steel projectile with a starting velocity was carried out by the finite element method in a three-dimensional formulation.
