“…They claimed that the model underpredicted the experimental findings by 19%. Additionally, using finite element analysis, Abada et al, [7] investigated sandwich structures made of steel plate and aluminium foam for the usage of armoured vehicles, while Avachat [6] explored the use of composite materials for blast mitigation in marine structures. Burns [8] has provided the study and modelling of the explosive containment box in airplanes.…”

The shock wave resulting from the explosion process is the main burden on the technical infrastructure facilities or people in contact with the epicentre of the high explosive (HE). The article presents the tests of EN C45 steel pipe of 10 mm thickness buried beneath the earth as a result of the impulse load of the detonation wave of the explosive charge. This process was modelled in one way using Abaqus Explicit code software using a 75 g Tri-Nitro Toluene (TNT) position 30 mm above the steel pipe. As a result of detonation, the samples were not fragmented, but visibly deformed displaying faster travelling of the explosion wave in air than in the soil. The main purpose of the work was to verify the impact resistance of EN C45 steel, which is commonly used in technical facilities. The impact numerical model results as a result of the shock wave on the steel tested material in the areas subjected to dynamic deformation are presented. The method used in this work is Coupled Eulerian-Lagrangian Method (CEL).
