摘要

The paper presents numerical and experimental results of the impact interaction between metallic solid bodies in the velocity range from 1400 to 15,000 m/s. Within Lagrangian continuum mechanics, fragmentation and perforation processes are analyzed for both steel and aluminum projectiles interacting with monolithic metallic barriers, including semi-infinite and layered targets. Numerical modeling is performed in three-dimensional formulation by the finite element method implemented in the software package EFES 2.0 to demonstrate the failure algorithm of simulating the formation of new contact, free surface and erosive fracture of materials. Adequacy of the mathematical model and numerical method is confirmed by a comparison with the available experimental data. The influence of the impact velocity, particle size, and target configuration on the dynamic behavior and failure mechanisms of both the projectile and the target is investigated herein.
