Coupled boundary element method and finite element method for hydroelastic analysis of floating plate

Journal of Ocean Engineering and Science, 2018
In this study, a numerical procedure has been proposed to analyze the equation of motion of the elastic plate which is elastic in nature and having shallow draft (small thickness) with arbitrary geometry subjected to linear wave force at a fixed ...

Consistent dirichlet boundary conditions for numerical solution of moving boundary problems [PDF]

, 2008
We consider the imposition of Dirichlet boundary conditions in the finite element mod-elling of moving boundary problems in one and two dimensions for which the total mass is prescribed.

Modification of boundary condition for the optimization of natural frequencies of plate structures with fluid loading

Advances in Mechanical Engineering, 2018
A finite element method, boundary element method, and genetic algorithm combined method is developed for the optimization of natural frequencies of fluid-loaded plates. In this method, the coupled finite element method–boundary element method is used for

A Galerkin boundary element method for high frequency scattering by convex polygons [PDF]

, 2007
In this paper we consider the problem of time-harmonic acoustic scattering in two dimensions by convex polygons. Standard boundary or finite element methods for acoustic scattering problems have a computational cost that grows at least linearly as a ...

The Boundary Element Method in Acoustics: A Survey

Applied Sciences, 2019
The boundary element method (BEM) in the context of acoustics or Helmholtz problems is reviewed in this paper. The basis of the BEM is initially developed for Laplace’s equation. The boundary integral equation formulations for the standard interior

Weak imposition of Signorini boundary conditions on the boundary element method [PDF]

, 2020
We derive and analyse a boundary element formulation for boundary conditions involving inequalities. In particular, we focus on Signorini contact conditions.

Dynamic Damage Quantification of Slab Tracks—Finite Element Models on Winkler Soil and Finite-Element Boundary-Element Models on Continuous Soil

CivilEng, 2022
Train passages over intact or damaged slab tracks on different soils were calculated by two methods. The finite element method (FEM) uses a Winkler soil under the track model by adding a thin “soil layer”.
