The topic of this paper is the fragmentation of concrete due to explosive loading. A meshfree Lagrangian method called smooth particle hydrodynamics (SPH) is used in the numerical simulation. A macroscopic constitutive law for concrete is implemented in the SPH-Code. It is shown that the SPH-method is able to simulate the damage of concrete slabs under contact detonation. The numerical results are compared with the data from two tests. The good agreement between them suggests that the SPH-program can predict the correct maximum pressures as well as the damage of the concrete slabs. Finally the fragment distributions of the tests and the numerical calculations are compared.
