Journal ArticleDOI
An ES-FEM for accurate analysis of 3D mid-frequency acoustics using tetrahedron mesh
TL;DR: In this article, an edge-based smoothed finite element method (ES-FEM) is proposed to solve 3D acoustic problems in the mid-frequency range, using the simplest linear tetrahedron meshes that can be generated automatically for complicated geometry.
Journal ArticleDOI
An edge-based smoothed tetrahedron finite element method (ES-T-FEM) for 3D static and dynamic problems
TL;DR: A novel domain-based selective scheme is proposed leading to a combined ES-T-/NS-FEM model that is immune from volumetric locking and hence works well for nearly incompressible materials.
Journal ArticleDOI
Design optimization of a novel NPR crash box based on multi-objective genetic algorithm
TL;DR: In this paper, the authors proposed a new structure with negative Poisson's ratio (NPR) crash box to improve the performance of the traditional crash box and the aluminum foam filled crash box.
Journal ArticleDOI
Dispersion error reduction for acoustic problems using the edge‐based smoothed finite element method (ES‐FEM)
TL;DR: In this article, a detailed analysis on the numerical dispersion error in solving 2D acoustic problems governed by the Helmholtz equation using the edge-based smoothed finite element method (ES-FEM), in comparison with the standard FEM, is presented.
Journal ArticleDOI
Coupled analysis of 3D structural-acoustic problems using the edge-based smoothed finite element method/finite element method
TL;DR: In this paper, a coupled ES-FEM/FEM method for structural-acoustic problems is presented, in which the ES-fEM and FEM models are used to simulate the structure and the fluid, respectively.
