Sažetak
According to the Ordinance on liquefied petroleum gas (LPG), the storage of gas cylinders is usually carried out in the open space. Since this storage space is in most cases located next to the fuel supply station whereby the safety distance of the bottle storage to any possible permanent ignition source is 5 meters, there is always a potential risk of explosion. In order to show how the material of the gas cylinders behaves at the explosion, the impact of the air blast was simulated. The gas cylinder used for the analysis was a capacity of up to 10 kg. The 3D model of the gas cylinder was made in SolidWorks according to 10 HRN MZ2.510 regulative and numerical analysis was made in Abaqus and in Ls-Dyna. The initiation of the explosion is set at different distances from the gas cylinder starting from the 5 meters and closer, and also it is time-dependent. For the explosion model, 10 kg, 50 kg and 100 kg of TNT charging were used.
