Abstract

In order to accurately simulate the dynamic response process of ceramic composite target under the penetration of 7.62 mm steel core projectile in ballistic test., this paper selects FEM (Finite Element Method), SPH (Smoothed Particle Hydrodynamics), SPH-FEM fixed coupling algorithm, SPH-FEM adaptive coupling algorithm as the simulation scheme, and uses LS-DYNA finite element software to analyze the penetration of small-caliber bullets. The research shows that: by analyzing the dynamic response process of ceramic failure and the residual velocity of the projectile, the FEM-SPH adaptive coupling algorithm can simulate the failure modes of ceramics at each stage, and quantify the simulation accuracy with the residual velocity of the projectile. The error of the adaptive coupling algorithm is 1.17%. The FEM-SPH adaptive coupling simulation model is reasonably applied to simulate the impact process of the bullet penetrating the ceramic target.
