Ultra high performance concrete (UHPC) is a cementitious composite, which exhibits superior qualities such as high-strength and durability. The present study aims at the response analysis of UHPC subjected to low -velocity impact loading. Three dimensional models for the target and the projectile are developed by using finite element method (FEM). The target is UHPC slab having dimensions - 300 x 300 x 30 mm. Steel projectile is used in the present study. The projectile is flat nosed and cylindrical in shape having diameter of 50 mm and length of 100 mm. The impact speed of the projectile is 25 m/s. The constitutive material model used for UHPC is concrete damage plasticity (CDP) model. The projectile is modelled to exhibit elastic-plastic hardening behaviour. The response of UHPC is compared with that of the normal concrete. Damage wave propagation and the penetration depths obtained from the simulation shows that UHPC performs better than the normal concrete, when subjected to low-velocity impact.
