Abstract
本稿では，安定化ISPH 法およびASI-Gauss 法の基礎理論と粒子-はり要素連成モデルについて説明した後，開発する連成解析手法の計算フローについて述べる．最後に，開発手法を用いていくつかのベンチマーク問題を解き，その妥当性を検証する．
In this research, we developed a partitioned FSI analysis method with a coupling stabilized ISPH method and ASI-Gauss method aimed for tsunami and buildings interaction problems. For transmission of physical quantities between fluid and structure domains, we adopted a particle-beam element interaction model based on Improved Explicitly Represented Polygon (IERP) wall boundary model. According to the numerical results simulating a free falling square column member into a water obtained by the developed method, it is confirmed that the balance between buoyancy and gravity, and rotation angle of the floating member at equilibrium state can be reproduced.
