“…Jama et al [11] have tried to quantify the energy dissipated during the local and global deformation mechanism of steel hollow sections subjected to transverse explosive loads. It has been highlighted that more than 50% of the total energy was dissipated during local deformations, whilst the remainder was dissipated due to plastic deformations.…”

“…It has been highlighted that more than 50% of the total energy was dissipated during local deformations, whilst the remainder was dissipated due to plastic deformations. In addition, an analytical method based on rigid-plastic analysis and yield line analysis has been developed by Jama et al [11]. As local and global deformations of near-field detonations are considerably involved in non-linear large plastic deformation analysis, it is recommended to have a non-linear analysis in order to obtain accurate results.…”

Numerical simulations of response of tubular steel beams to close-range explosions AbstractA numerical study of hollow and concrete-filled square tubular steel columns subjected to near-field detonations has been undertaken and validated through the experimental results. The experiments used concrete-filled and hollow square tubular columns (100 x 5 mm SHS Grade C350) made out of cold-formed structural steel hollow sections (SHS) that were simply supported at both ends. High explosives TNT charges were placed above the top surface of the column at two different scaled standoff distances of 0.12 m/kg1/3 and 0.15 m/kg1/3. Failure patterns and permanent mid-span deformations were recorded and compared with the numerical analysis results. Arbitrary Lagrangian-Eulerian (ALE) formulations coupled with fluid-structure interaction (FSI) algorithms that are available in the advanced finite element code LS-DYNA were used in the numerical study. A detailed description of the numerical technique adopted in the study is presented. The models were validated with the experimental results and were used to obtain the failure pattern, permanent plastic deformation, pressure and impulse time histories, stress distribution, and energy absorption of the different configurations of the columns. The performance of hollow and concrete-filled SHS tubes for blast load mitigation was assessed and discussed.

“…Kouretzis et al 17 simplified the pipe into a three-dimensional thin elastic columnar wall with analytical methods to deduce the function expression of stress-strain distribution in the pipe during explosion loading. Jama et al 18,19 analyzed the overall and partial deformation of square steel pipe through numerical simulation and experimental method and came to the results that the hardening effect of strain rate was very important to predict the whole and local deformation of the beam, which turned out the thermal softening should not be ignored. Lu et al 20 carried out an experiment to study the impact of the acetylene-air mixed gas explosion shock wave on the scaled thin-walled cylindrical shell model and obtained the dynamic response characteristics of the thin-walled cylindrical shell structure under the combustible gas explosion.…”

An experimental platform of gas cloud deflagration is built in this study, and the propane-air premixed gas blasting experiment was carried out in curved pipes with different lengths. The effect of pipe length on combustible gas explosion and the influence of explosion shock wave on thin-walled pipe loading were also studied. The experimental device included photoelectric, pressure, and strain sensors which were used to evaluate the explosion parameters and stress of the thin-walled pipe. The result was that the longer the pipeline, the higher the wall overpressure and the bigger the maximum tube wall. The pressure time curve was consistent with the thin-walled strain time-history curve. The pipe bend accelerates the flame propagation to a certain extent, and the pipe length influenced the law of flame ignition and explosion in pipe integrally; the longer the pipe, the greater the pressure and the speed of the flame. The maximum explosion pressure appears at the end of the pipe, and the loading of the shock wave on pipe wall belongs to dynamic response.
