FEM Source Effect Investigation with 2.5D Numerical Modelling
Near Surface 2009 - 15th EAGE European Meeting of Environmental and Engineering Geophysics, 2009Land-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, 2011The 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.

Yacs - A New 2.5D FEM Eigenmode Solver for Axisymmetric RF-Structures
2015Most feasibility studies for modern accelerator concepts, including superconducting multicell RF-cavity-resonators in circular accelerators, depend on computing a large number of eigenmode frequencies and field patterns to obtain typical figures of merit. This task includes computational intensive numerical studies.

Ground Vibration Induced by Moving Train Loads on Unsaturated Ground Using 2.5D FEM
2020Vibration of an unsaturated ground subjected to moving train loads is investigated using a two-and-a-half-dimensional finite element method (2.5D FEM). The track system is simplified as an Euler beam resting on the unsaturated porous medium, the governing equations are transformed to the frequency–wavenumber domain, and the results in time-space domain

Cu pattern density impacts on 2.5D TSI warpage using experimental and FEM analysis
2014 IEEE 64th Electronic Components and Technology Conference (ECTC), 2014Through Silicon Interposer (TSI) needs to fulfill multi-die stacking in one packaging which can bring high integration density, short interconnection length and small size for next generation devices. Die stacking is a key process in the TSI manufacturing flow, and within that process, die warpage is of central concern.

Investigating ground vibration induced by moving train loads on unsaturated ground using 2.5D FEM
Soil Dynamics and Earthquake Engineering, 2019Abstract A two-and-a-half-dimensional finite element method (2.5D FEM) is applied to investigate the dynamic response of an unsaturated ground subjected to moving loads caused by high-speed train. The partial differential equations of unsaturated porous medium in frequency domain are deduced based on the equations of motion and mass conservation of ...

Preliminary Analysis of the Interaction Between Tunnel and Soil by the 2.5D FEM-BEM Method
2017In this paper, both the full space and the half space 2.5 dimensional finite element-boundary element model is established for modeling the coupled tunnel and soil. The tunnel wall is modeled by using finite element method and the soil is modeled by using boundary element method.

The Analysis of Unsaturated Ground Vibration Induced by Train Loading by 2.5D FEM
2017Two kinds of numerical models for unsaturated porous medium are used to simulate the unsaturated ground vibration induced by train loading, to study the influences of saturation on ground vibration and to discuss the differences of the two numerical models.

Soil Dynamics and Earthquake Engineering, 2012
Abstract The first part of the paper includes a brief presentation of a 2.5 D FEM-BEM model, developed by the authors, which is able to lead with problems of vibrations induced by traffic including the train–track dynamic interaction. Then a global description of a test site developed on a stretch of the Portuguese railway network is presented.
