An edge-based smoothed finite element method (ES-FEM) for dynamic analysis of 2D Fluid-Solid interaction problems

Nguyen-Thoi, T. / Phung-Van, P. / Ho-Huu, V. / Le-Anh, L.

Abstract The paper presents an extension of the Edge-based Smoothed Finite Element Method (ES-FEM-T3) using triangular elements for the dynamic response analysis of two-dimension fluid-solid interaction problems based on the pressure-displacement formulation. In the proposed method, both the displacement in the solid domain and the pressure in the fluid domain are smoothed by the gradient smoothing technique based on the smoothing domains associated with the edges of the triangular elements. Thanks to the softening effect of the gradient smoothing technique used in the ES-FEM-T3, the numerical solutions for the coupled systems by the ES-FEMT3 are improved significantly compared to those by some other existing FEM methods.
