Abstract
In order to understand the characteristics of projectile penetrating obliquely into multi-layered spaced concrete targets with no attack angle, a series of numerical simulation of the process of projectile penetrating into target is done by the finite element code LS-DYNA 3D. The basic phenomena of oblique penetration is described in detail, the variation regularity of acceleration in X and Y direction is analyzed, the effects of targets' space and number of layers on anti-penetrated performance are obtained. The research indicates that when the total thickness is invariable the decrease of space or increase of number can debase the anti-penetrated performance of target. But the anti-penetrated performance will change little with the increase of number if the number of layers is magnitude. The results have reference value for the build of contravallation and underground blindage.关键词
