영문 초록

The characteristics of a secondary disaster are not well known with respect to the drift-impact by storm surge or tsunami. A numerical analysis for understanding the characteristics of a secondary disaster must be capable of simulating fluid dynamics as well as structural behaviors. In this sense, a fluid-structure interaction analysis is necessary with specialized numerical model such as LS-DYNA. In this study, we numerically simulated the breakaway-drift-impact process of a container due to break waves using LS-DYNA, and additionally examined the applicability of the model. Furthermore, we investigated the validity and effectiveness of an LS-DYNA analysis through the wave pressure comparison of measured values in a hydraulic experiment and the calculated values. In the analysis of drift-impact of a container due to dam-break waves, the drift velocity had a dominant effect, which is in line with previous experiments. In the collision analysis of drifting object due to storm surge/tsunami, the LS-DYNA simulation was proven as an appropriate numerical approach in this study.
