“…Results of experiments [1][2][3][4] with various-scale, geometrically similar, spherical and cylindrical shells of structural steels under internal explosive loading (with the cavity filled with water and air) unambiguously indicate the possibility of the occurrence of a strong scale effect of an energetic nature (SEEN) [5], which decreases the ultimate specific load-bearing capacity ξ [the ratio of the ultimate mass of the high explosive (HE) whose explosion results in no shell failure to the shell mass] and deformability with a geometrically similar increase in the shell dimensions. For steel structures, the SEEN becomes especially pronounced in going from cylindrical to spherical shell [1,2] because of a decrease in shell plasticity and deformability with an increase in the stress biaxiality and specific elastic-strain energy.…”

Experimental data on the dynamic response and strength of simple shells of fiber composites are used to justify the choice of these materials for the load-bearing shells of blast-proof structures. It is shown that in such structures composites are preferred to homogeneous metal alloys (structural steels) to eliminate strong scale effects of an energetic nature. A criterion for selecting fibers is proposed and justified experimentally, and reinforcement patterns are determined to obtain optimal (in the strength-mass ratio) compositions for the load-bearing shells of blast-proof containers and chambers.

The fragments generated by explosions of storage tanks in chemical industrial parks may cause perforations or dents in adjacent tanks and trigger a domino effect. This paper determined reasonable fragment parameters based on the statistical laws of accidents and empirical formulas. The dynamic response process of large steel tanks impacted by fragments was simulated with LS-DYNA. The typical impact process and results were analyzed in detail, and the damage laws of the tanks were discussed under various filling coefficients, volumes, fragment velocities, and impact angles. The results indicate that the inertial resistance of the inner liquid shortens the impact duration. Multiple collisions between the fragment and tank during impact, and the impact process involves three stages: initial collision, crushing and collision, and separation flight. The impact center displacement shows a fast and then slow reduction trend as the liquid level height increases, and the damage to the tank is negatively correlated with the liquid level height. The damage is lower when the tank volume is larger in an empty tank or at a high liquid level, while the damage instead increases when the volume exceeds 5000 m3 at a low liquid level. The peak impact force of the end-cap fragment is greatest when frontal impact occurs. Fragment flipping and curling occur at 45° and 90° impact, respectively. As the vertical impact angle increases from 0° to 90°, the fragment impact mode changes from initial frontal impact to flip detachment and finally to curling deformation.
