Experimental and Theoretical Study of Space Debris Impacts on Shielded Targets
A comprehensive study is reported on high- and hypervelocity impacts of a steel ball simulating a space debris particle on shielded targets. Experimental studies of high-velocity impact of a steel ball were performed in the velocity range up to 2500 m/s. The obtained data were used to verify the mathematical model and numerical algorithm. Numerical simulation of the space debris impact on a shielded target was carried out in the impact velocity range 1400–7000 m/s using the finite element method implemented in the original EFES software package. The proposed failure algorithm can describe the material fragmentation and the formation of new contact boundaries without computational mesh distortion. The specific features of shock wave processes and the destruction of the target and ball were investigated at different impact velocities.
期刊介绍：
The journal provides an international medium for the publication of theoretical and experimental studies and reviews related in the physical mesomechanics and also solid-state physics, mechanics, materials science, geodynamics, non-destructive testing and in a large number of other fields where the physical mesomechanics may be used extensively. Papers dealing with the processing, characterization, structure and physical properties and computational aspects of the mesomechanics of heterogeneous media, fracture mesomechanics, physical mesomechanics of materials, mesomechanics applications for geodynamics and tectonics, mesomechanics of smart materials and materials for electronics, non-destructive testing are viewed as suitable for publication.
