Abstract

The paper reports on experiments and numerical simulation of high-speed impact loading of additively manufactured heterogeneous specimens. It is shown that the proposed model of direct numerical simulation of a heterogeneous material based on random distribution of given materials over difference cells accurately reproduces the processes of deformation, fracture, and cratering under impact loading. A series of calculations are made to determine the ballistic efficiency of additively manufactured heterogeneous metal-ceramic specimens using the DoP (depth-of-penetration) method. A procedure is proposed for estimating the efficiency of heterogeneous metal-ceramic specimens, revealing local maxima in it.

增材制造非均质金属陶瓷试样对动态冲击的响应建模

本文报道了增材制造非均质试样高速冲击载荷的试验和数值模拟。结果表明，基于给定材料在不同单元上的随机分布，所提出的非均质材料的直接数值模拟模型能够准确地再现冲击载荷下的变形、断裂和成坑过程。用DoP（侵彻深度）法对增材制造非均质金属陶瓷试样的弹道效率进行了一系列计算。提出了一种估算非均质金属陶瓷样品效率的方法，揭示了其中的局部最大值。
