Abstract
En 中文
Impact damage to adjacent tanks caused by fragments is a critical initiating event in domino accidents. To clarify the deformation and fracture characteristics of horizontal tanks subjected to fragment impact, the impact experiments were conducted with end-cap fragments at various velocities and under different filling conditions. A fluid-structure interaction model was developed based on the Coupled Eulerian-Lagrangian (CEL) method to simulate the deformation and rupture limits of tanks with different dimensions and filling conditions under fragment impact. Through dimensional analysis, a dimensionless empirical formula for predicting the maximum transverse deflection was proposed. The results indicate that liquid-filled and pressurized conditions concentrate impact energy near the impact point, thereby reducing the impact resistance of the tank and altering the failure mode. The proposed empirical formula effectively predicted the maximum transverse deflection of tanks with varying dimensions and filling conditions subjected to end-cap fragment impact. A practical engineering tool for the vulnerability assessment of horizontal storage tanks under fragment impact is provided.
