摘要
Based on the theory of slip line and compared with the subject research of rigid stamping die press into semi-infinite rigid-plastic media, the crater depth formula of rigid-plastic projectile penetration concrete considering internal friction angle is established. Moreover, the relationship between the internal friction angle and impact velocity is researched by the Mohr-Coulomb theory and combined with the strength dynamic effect, and the conclusion in this paper is compared with the penetration test result of UHMWPE fiber reinforced concrete. The result shows that, the crater depth will be deeper as the internal friction angle increases and the internal friction angle will be larger with the increasing of the impact velocity.
