Simulation on Equivalence between Layered Space Plates and Homogeneous Steel Impacted by a Tungsten Sphere

摘要

To research on the equivalent of perforating through layered space plates and homogeneous steel, based on the rule that the limit penetrating velocity, the penetration process of tungsten sphere into layered space plates and homogeneous steel was simulated with LS-DYNA finite element code, the numerical results corresponded well to previous experimental observation. The expression between layered space plates and homogeneous steel impacted by a tungsten sphere was presented through analyzing the numerical results.
