Abstract

In this work, within the framework of the Lagrangian approach, the hypervelocity interaction (HVI) of an aluminum particle, representing space debris, with monolithic and spaced barriers made of aluminum alloy of equivalent thickness is numerically studied using the finite element method. The simulation is performed using the proprietary 3D software complex EFES, which ensures mass conservation under the fracture condition. The implemented fracture algorithm allows for the description of material fragmentation and the formation of new contact boundaries without distorting the computational mesh. A comparison with experimental data on crater depth under hypervelocity impact has been conducted. The protective properties of monolithic and spaced barriers were evaluated in the velocity range of 3–15 km/s.
