Abstract

In the presented work, numerical experiments were carried out in the framework of the molecular dynamics method to study the impact interaction of metallic nanoclusters of different sizes with a metallic substrate in a wide range of velocities. Analysis of the obtained data showed that the crater volume remains proportional to the impact energy and inversely proportional to the dynamic strength of the material, with the direct angle coefficient being independent of the cluster size and the cluster-substrate material.
