摘要

Within the framework of the Lagrangian approach, the numerical finite element method is employed to study both normal and oblique high-speed and hypervelocity impacts (HVIs) of an aluminum particle simulating space debris on solid aluminum, steel mesh (discrete), and two-layer metal-ceramic screens consisting of an upper layer made of ceramic B4C and a lower layer composed of either monolithic aluminum or a steel mesh. All screen types had identical surface densities. Simulations were conducted using the authors’ proprietary three-dimensional software package EFES ensuring mass conservation under failure conditions. The implemented failure algorithm enables accurate description of material fragmentation and formation of new contact boundaries without distortion of the computational grid. Evaluation of the effectiveness of protective properties for various protective screens was carried out within a velocity range spanning from 3 to 10 km/s.
