3D aspects in a 2.5D BEM/FEM code for soil structure interaction
, 2020 Some limits of 2.5D models for sol-structure interaction are addressed. First, the problem of micro piles is studied in comparison with 3D FEM full models. In the 2.5D model, micro-piles are replaced by walls of a given thickness which was found to be directly correlated to the 3D pile density.

Numerical simulation in roll pass design for bar rolling
Metalurgija, 2015 The application of finite element simulation to the problem of roll pass design for round bar rolling is considered. Two roll pass sequences were developed by analytical methods and then optimized using 2.5D Finite Element Method (FEM).

Environmental vibration reduction characteristics of subway track with resilient wheel
Frontiers in PhysicsEnvironmental vibrations induced by subway systems are typically mitigated through track-based isolation measures, which are effective only in localized areas. Extending such solutions along entire lines involves prohibitive costs.

Modeling of vibrations induced in tunnels: a 2.5D FEM-PML approach
Geotecnia, 2018 A simulação e o estudo da problemática das vibrações induzidas pelo tráfego ferroviário em túneis é uma tarefa difícil e complexa. O carácter semi-indefinido do domínio circundante do túnel associado às características tridimensionais do problema são os principais responsáveis pela complexidade do problema.

Tunnelling and Underground Space Technology, 2020 In this paper, a comprehensive numerical approach for modelling track/tunnel/soil systems in the context of ground-borne railway-induced vibration problems considering a full-space model of the soil is proposed. All the approach is formulated in the wavenumber-frequency domain and it consists of a coupled finite element–boundary element model of the ...
