Numerical simulation of steel tube array composite armor structure against rod projectile penetration

In order to explore the feasibility of the new type of armor against projectile penetration, a steel plate tube array composite armor was designed, and its effectiveness against projectile penetration was studied by numerical simulation. The results of simulation vividly reproduce the physical and mechanical processes of composite armor structure, such as deformation and breakage, penetration failure, and stress wave propagation under the impact of projectile. The time history characteristics of projectile residual velocity were accurately captured. The influence of key factors, such as the number of tube array layers, array combination form and projectile impact position on the damage mode of the composite armor structure was obtained. The related results can provide important support and scientific basis for the optimal design and accurate evaluation of the new composite armor.
