A 2.5D FEM analysis of E-plane structures

2014 International Conference on Numerical Electromagnetic Modeling and Optimization for RF, Microwave, and Terahertz Applications (NEMO), 2014
This paper present a 2.5D FEM analysis of E-plane waveguide structures. A mixed formulation is used and the work is the basis of a more general analysis tool for 3D structures by 2.5D FEM. In order to verify the accuracy of the method, an E-plane low pass filter has been analyzed and the results have been compared with mode-matching and with ...

Vibrations induced by railway traffic in buildings: Experimental validation of a sub-structuring methodology based on 2.5D FEM-MFS and 3D FEM

Engineering Structures, 2021
Abstract The assessment of vibrations induced by railway traffic is a complex issue that demands numerical tools for prediction of its generation and propagation along the track-ground-building system. For that purpose, this paper presents a 2.5D FEM-MFS model for modelling the track-ground system, where the Finite Element Method (FEM) is used to ...

FEM Simulation of Single-Grit Grinding on a 2.5D Woven Composite

Transactions of Tianjin University, 2017
Single-grit grinding of a 2.5D woven composite was investigated by the finite-element method (FEM) using a unit-cell model. According to our hypotheses, the axis of the warp yarn was a sinusoidal curve and the cross section of the weft yarn was shaped like a biconvex lens. AVUMAT subroutine was used to construct the constitutive model of the 2.5D woven

2.5D MFS–FEM model for the prediction of vibrations due to underground railway traffic

Engineering Structures, 2015
Abstract Vibrations induced by underground railway traffic have been receiving special attention from the technical and scientific communities, and different models for their prediction can be found in the literature. Since the tunnel can be seen as a longitudinally invariant structure, a 2.5D approach can be applied, minimizing the computational ...

2.5D coupled FEM-SBFEM analysis of ground vibrations induced by train movement

Soil Dynamics and Earthquake Engineering, 2018
Abstract 2.5D models are efficient tools for dynamic analysis of structures that are longitudinally invariant. In this work, a two-and-a-half dimensional (2.5D) coupled finite element method-scaled boundary finite-element method (FEM-SBFEM) is utilized to study the induced ground vibration of passing trains.

FEM Source Effect Investigation with 2.5D Numerical Modelling

Near Surface 2009 - 15th EAGE European Meeting of Environmental and Engineering Geophysics, 2009
Land-based controlled-source frequency domain electromagnetic methods (FEM) using horizontal electrical dipole (HED) source create a lot of interpretational problems associated with the finite transmitter-receiver distance and with conductivity inhomogeneities in the vicinity of the transmitter.

2.5D FEM Study and Optimization of Roll Pass Design in Roughing Mill Group

Materials Science Forum, 2011
The subject of the paper is a study of the material behaviour during hot rolling. The process considered is a rolling of round bar in roughing mill group which consist of four passes. The computer simulation of the process shows that the local plastic deformations which appear in the material are extremely large.
