Simulation of the Impact of a Steel Ball on an Aluminum Plate D16 and Comparison with the Experiment

The article investigated the process of penetration of an aluminum plate by a steel ball at speeds from 600 to 1000 m/s. A numerical simulation of the impact of the ball was carried out and compared with the results of experiments in which the ball was accelerated using a powder accelerator. Numerical models were developed using the explicit finite element method in LS-DYNA software. The influence of material properties and model parameters on the penetration process is analyzed. A good agreement between numerical and experimental results has been achieved.
