“…A schematic representation is given in Figure 4(c). A square section explosive driven shock tube (EDST) is used to generate a planar blast wave at its end [17]. The used EDST is a steel square section tube with an inner edge of 70 mm, a thickness of 5 mm, and a length of 1 m. At the entrance, the tube is reinforced over the first 150 mm.…”

The present paper focuses on the study of the effectiveness of the sacrificial cladding using polymeric foam as crushable core to reduce the delivered blast energy using a simplified structure. The latter consists of a simply supported steel beam under a localized blast load. The tested sacrificial cladding has a cross-sectional area of 80 × 80 mm2. The effect of the front plate mass and the crushable core properties (plateau stress and thickness) is studied. Three polymeric foams are investigated: (a) the expanded polystyrene foam (PS13) with a density of 13 kg/m3, (b) the closed-cell polyurethane (PU30) with a density of 30 kg/m3, and (c) the open-cell polyurethane (PU50) with a density of 50 kg/m3. Four front plate masses are used: 144, 188, 336, and 495 g. All possible combinations are tested to determine their absorption capacity. The obtained results show that the absorption capability increases by increasing the front plate mass, the plateau stress, and the thickness of the crushable core. The open-cell polyurethane PU50 performs better. Disintegration problems are observed on the expanded polystyrene PS13 after the end of the compression process.

“…This also contributes to higher quality measurements due to the absence of smoke and attenuated flare. A detailed description of the working principle of the EDST can be found in the work of Ousji et al [16]. The EDST is a thin-walled steel square section tube with an edge of 300 mm, 5 mm thick and 1.5 m long.…”

“…Instead, a material fraction rule is applied to the air do- main volume where the explosive material would be located. Assuming a combined pressure/impulse TNT equivalent factor of 1.28, a C4 density of 1.6 g/cm 3 and knowing that the explosive charge used in the experimental program was 2.8 g of C4 detonated by 1 g of TNT (from the electrical detonator), an equivalent C4 sphere is defined with a radius R = 8.42 mm, corresponding to an equivalent explosive charge of 3.61 g of C4 [18]. The centre of the explosive charge is located at a distance R from the concrete.…”
