For the first time, it is shown that the separation of sheet plates reduces its impact resistance compared to the variant when the plates of the barrier are placed side by side. The microstructure study was used to determine the deformation features of St.3 and high-strength steel Miilux 500 under impact compression. Numerical simulation shows that taking into account the influence of the strain rate on the material behavior allows to increase the level of reliability of modeling the impact contact between the projectile and the barrier.  Product Description popup.authors popup.nrat_date 2023-04-06 Close
