The characteristics of perforation damage for thin cylinders suffered by high velocity impact is different from that of thin plates because of the curvature. In this paper, numerical investigation on the perforation damage behavior for thin steel cylinder pipes with different radial diameters is performed with the use of LS-DYNA3D program and smoothed partide hydrodynamics finite element method (SPH-FEM) algorithm. Based on the physics mechanics characteristics of thin plate impacted by fragment projectile at high velocity, perforation can be simplified as two stages, initial fluid dynamical piercing and the following inertia piercing, and a new simplified physics model has been proposed to illustrate the perforation process. The effect of the diameter of the pipes has been discussed on the difference ratio between axial diameter size and the radial size of the perforation hole. The result shows that the perforation displays oval in shape and the axial size of the hole is a little longer than the radial size. For the range of 2-3 km/s, the difference ratio decreases with the diameter of the thin cylinder pipe increasing. What's more, the distribution of debris cloud after perforation shows sensitive to the diameter of cylinder pipes. Under the similar impact condition, it reveals that cylinder pipes with larger diameter tend to produce relatively larger expansion angle and larger residual velocity of the debris.
