ABSTRACT
This paper gives full analysis of the local failure of reinforced concrete slabs subjected to soft
missile impact, where the missile is a deformable object, by using three-dimensional dynamic
finite element analyses in which provision is made for the simulation of impact loads, plasticity
and cracking of concrete. An assessment is made of perforation and scabbing. Three
computer programs: NONSAP, MARC and OBAID have been used for comparison. The
analytical results are well compared with those available from a model test. These results are
very useful in the process of design of reinforced concrete slabs and give them integrity
against hazards.
