Abstract:
Numerical simulation of the processes of high-speed loading of homogeneous and heterogeneous targets by single projectiles, as well as by a group of projectiles with the same parameters in mass and momentum, has been carried out. Based on a comparison of the numerical simulation results for loading targets with different sets of projectiles, it is found that a projectile in the form of a ring knocks out the maximum hole in the target in terms of geometric dimensions, while a set of seven small disks removes the maximum mass from the target. The ring impact forms a continuous spall plate, which outruns the cloud of fragments of the destroyed material. Adding more than 5% of ceramics to the aluminum target volume does not allow the projectiles to penetrate through.
The research was supported by the Ministry of Science and Higher Education of the Russian Federation within the framework of the state assignment (project No. 121030500137-5) and partly supported by RFBR Grant No. 19-08-00906.
