    Investigation of the Sloshing Behavior Due to Seismic Excitations Considering Two-Way Coupling of the Fluid and the Structure
    (MDPI, 2019-12-17) Dincer, A. Ersin
    Sloshing behavior due to near-fault type and earthquake excitations of a fluid in a tank having a highly deformable elastic structure in the middle was investigated experimentally and numerically in this paper. In the numerical model, fluid was simulated with smoothed particle hydrodynamics (SPH) and structure was simulated with the finite element method (FEM). The coupling was satisfied with contact mechanics. The delta-SPH scheme was adapted to lower the numerical oscillations. The proposed fluid-structure interaction (FSI) method can simulate the violent fluid-structure interaction problem successfully. The effects of near-fault type and earthquake excitations on free-surfaces of fluid and the elastic structure are presented.

    Hydro-Elastic Analysis of Standing Submerged Structures Under Seismic Excitations With SPH-FEM Approach
    (Latin Amer J Solids Structures, 2020) Demir, Abdullah
    In this paper, a fully coupled fluid structure interaction (FSI) method is used to investigate the hydro-elastic response of a fully submerged standing structure under seismic excitations. Two different domains (solid and fluid) are modelled by mesh based and meshless methods, respectively. Solid domain is modeled by finite element method (FEM) and fluid domain is modeled by smoothed particle hydrodynamics (SPH). Coupling between FEM and SPH is implemented via contact mechanics, and this method differs from others in the way of coupling mechanism. Invading SPH particles are solved together with finite elements by using contact mechanics, then, a fully coupled method is achieved. In the scope of this research, different seismic excitations are applied to a rectangular tank. Half of the tank is filled with water and a submerged rubber plate is attached to its mid bottom. Thus, two-dimensional motion of rubber plate and water is investigated experimentally and simulated numerically. [GRAPHICS] .
