The hypervelocity impact interaction of the sphere projectile with continuous shield and mesh shield, which were the same thickness, was investigated numerically. The study involved the differences in the morphology and the distribution of velocity, mass and momentum of the debris clouds generated by impacting two kinds of shields. The calculations show that the morphologies of the debris cloud vary with the impact locations when a projectile impact the mesh shield, and there is the banded distribution of debris in the front of debris cloud. Comparison between the continuous shields and the mesh shields with the same thickness, the maximum of momentum density in the mesh shield was higher than it in the continuous shield. The mesh shield does not effectively slow the projectile resulting from the impact, but break up it. The dynamical response of the projectile varies with the shields. Impacting the mesh shield, the main of debris are at the rear end of the debris cloud, which is different from the continuous shield.
