Modeling accidental-type fluid-structure interaction problems with the SPH method

摘要

This paper presents the validation aspects of a unified numerical framework based on SPH formulation and devoted to the modeling of fluid-structure interaction problems involving large motion of the fluid and large deformation with a possible failure of the structure. The fluid domain is modeled according to an updated Lagrangian formulation. The solid domain (3D and shell models) uses the total Lagrangian formulation. The fluid-structure interaction is treated via a unilateral contact algorithm adapted to SPH context. The SPH framework is verified on academic test cases and validated by simulating an experiment involving the reservoir leakage.
