Abstract Summary
The shock wave resulting from the explosion process is the main burden on the technical infrastructure facilities or people in contact with the epicenter of the explosive explosion (MW). 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 two ways using Abaqus Explicit code software using a 75 g Tri-Nitro-Toluene (TNT) position 30 mm above the steel pipe and exactly within the 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 numerical model results on the impact 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). Keywords: shock load, shock wave, microscopic analysis, explosion modeling, steel C45
