Structures can be affected by accidental loads, for example a vehicle impact or blast and shock waves due to a detonation. These accidental loads may lead to local damages. If reinforced concrete is used as construction material, cracks occur not only in the central target area, but also in the surrounding material. Fig. 1 shows a RC-slab with a thickness of 20 cm, which has been loaded by a contact detonation (charge: 1 kg PETN). The central target area and the surrounding area are indicated in the figure.
