Abstract:

Ceramic materials have excellent mechanical properties such as light weight, great hardness and high compressive strength. This paper presents a numerical study on dynamic response of ceramic balls protected ultra-high performance concrete (UHPC) targets subjected to the high-velocity rigid projectile impact using the coupled smoothed particle hydrodynamics-finite element (SPH-FE) method in LS-DYNA. Numerical models are firstly validated, and then parametric studies are conducted to explore the effect of diameter, spatial arrangement and material type of ceramic balls as well as the impact position on the dynamic performance of UHPC targets. Compared with other existing UHPC slabs at the striking velocities from 500 m/s to 850 m/s, UHPC slabs protected with 6-layer hex-pack arranged ceramic balls with the diameter of 20 mm is most effective in terms of reducing the depth of penetration (DOP).
