Currently numerical modelling is used widely to evaluate the spacecraft persistence under the space debris impact. In the process of development, all the numerical codes are repeatedly tested using analytical solutions and experimental data obtained in conditions close to that of the application, to compare with. To use numerical codes for mopdelling of the hypervelocity impact with confidence, additional testing on problems reflecting key features associated with shielding against space debris is needed. KERNEL code based on SPH-method (Smoothed Particles Hydrodynamics) was developed at RFNC-VNIIEF specially for numerical simulation of three-dimensional motions of the continuous media with large deformation and fracture. Its testing using high- and hypervelocity impact experimental data showed practically full correspondence of the cavern dimensions in thick target, good agreement in dimensions of holes and fragmentation regions and reasonable agreement in geometry of the debris cloud in the case of perforation of the thin distanced sheets were obtained.
