The modeling of the process of forming elongated elements from segment liners for testing anti- meteoroidal protection for spacecraft

The results of mathematical modeling of the process of forming elongated element from segment charge liners for testing anti-meteoroid protection of spacecraft using numerical methods of continuum mechanics are considered. The paper presents options for improving such charges to increase their effectiveness. Data from computational experiments with various structural parameters of steel segment liners are described. In models with different physical and mechanical properties of the facings, the mechanism of forming an elongated element from the liners with a gradient in the radial direction of plasticity is demonstrated. It is shown that the control of physical and mechanical properties in the liners makes it possible to form filled and aerodynamically stable element. The application of the elastic-plastic deformation model and the fracture criterion in the form of the Smirnov-Alyaev criterion is justified.
