Abstract: This paper studies the impact of high-speed particles on corrugated metal mesh shields. Numerical solutions to a number of problems on high-speed interaction at different corrugation angles and positions of the initial contact point of the shield and impactor are solved using the grid Wilkins Lagrangian method in a three-dimensional formulation. The parameters of the behind-the-barrier cloud of destruction products are compared for various problems with the same distance traveled by the particle perforating the shield. Thus, the optimal inclination angle of the corrugation is revealed.

Keywords: high-speed impact, mesh shield, debris protection, numerical simulation.
