A Study on the Collision Forces Induced by the Floating Structures Washed onto the Apron by Tsunamis

Abstract

The present paper describes the collision forces induced by the floating structures washed onto the apron by tsunamis using the MPS method (Moving Particle Semi-implicit method). The effectiveness of application is also verified.The two dimensional MPS method is used in this paper. It explains the governing equations and the modeling of behavior of floating body in the MPS method in the beginning. Afterwards, the spatial resolutions and the collision forces are examined. The spatial resolutions are examined by adjusting the inter-particle distance. The collision forces are examined by comparing between the numerical results and the experimental results. From the comparison between the numerical results and the experimental results, the applicability of the MPS method is discussed.
