     this paper describes numerical missile impact analysis on a reinforced concrete slab using the finite element (fe) solver abaqus/explicit. the fe model of the impacted reinforced concrete slab resembles a structure used in the missile impact tests by hanchak et al. fe analyses with a hard (rigid) and a soft (deformable) missile and sensitivity studies related to the initial missile velocity are performed. traditional lagrangian formulations for both the missiles and reinforced concrete slabs are used. concrete damaged plasticity constitutive model for concrete in abaqus/explicit, is used and its suitability and limitations for missile impact analyses are explored. the concrete damaged plasticity model of abaqus/explicit leads to reasonable and sound results in terms of strains/stresses of the . reinforced concrete slab, overall energy balances and overall deformation of the concrete slab.
