Evaluation of seismic Vulnerability and Strengthening of heritage Buildings. Case Study: The Giralda of Seville
… model has been carried out. Both 2D and 3D Finite Elements Model (FEM) has been developed to analyse the settlements, considering the different construction phases, the loads, the time of execution and consolidation between phases. Therefore, the author has found that the tilt to the …

Measurements and finite element modelling of transformer flux with dc and power frequency current
… to excessive stray flux. Finite element matrix (FEM) modelling software is of considerable use in transformer engineering as it is able to solve electromagnetic fields in transformers. For many problems, typically involving only specific parts of a transformer, fairly accurate solutions can be …

Numerical modelling of the aluminium extrusion process and comparison with results obtained from industrially extruded complex sections.
… by the investigator in the BOAL plant. The 3D FEM module was used to study the required load, the temperature evolution, surface formation of the extrudate and material flow during the process. The effect of varying process conditions on the selected geometries were investigated and verified …

Biophysical Dynamics Of Rgs-Lov Proteins As Systems For Light-Induced Membrane Recruitment
… GTPase signaling. Here, I first report a 3D non-linear finite element model of the cell-wide spatiotemporal dynamics of BcLOV4 membrane recruitment. Inputs were data from single cells unique in morphology and initial absolute protein concentration, as opposed to fitting an idealized cell …

Hydraulic fracturing design for horizontal wells in the Bakken formation, Williston Basin
… reservoir simulation projects. </p><p> The fully 3D/FEM* fracture simulation showed that a fracturing treatment with injecting slickwater as the pad followed by crosslinked gel together with ceramic or resin-coated sand would guarantee that most proppants would stay within the Bakken Formation. …

Application of new observational method on deep excavation retaining wall design in London Clay
… back-analysed by the Mohr-Coulomb model using FEMs from Pseudo-FEM to 2D and 3D FEMs. The Crossrail Tottenham Court Road Station, Western Ticket Hall deep box excavation is also back-analysed by the BRICK model using the 3D FEM, representing the advanced soil model. The above back-analysis …

3D numerical modelling of brittle failure in mechanized excavation of deep tunnels
… only axisymmetric or fully threedimensional (3D) models are capable to study in detail the complex interaction between the rock mass, the tunnel machine and its system components, and the tunnel support. The most advanced and accurate models are the 3D models. It is seen however that very few …

Double Angle Framing Connections Subjected to Shear and Tension
… of double angle connections. For these purposes, 3D-nonlinear finite element models were developed to simulate the connection behavior under the three loading cases. The commercial software package, ABAQUS, was used for the study. The complex phenomena of contact problems and the pretension forces …

Applications of Intelligent Manufacturing and of Numerical/Analytical Modeling Techniques to Milling Processes
… the application of the finite element modeling (FEM) techniques to study manufacturing processes or to highlight behaviour of products, for example of cutting tools, during the design phase. The second technique deals with the manufacturing process control, and is aimed at the increasing of …

Free and Forced Vibration of Linearly Elastic and St. Venant-Kirchhoff Plates using the Third Order Shear and Normal Deformable Theory
Employing the Finite Element Method (FEM), we numerically study three problems involving free and forced vibrations of linearly and nonlinearly elastic plates with a third order shear and normal deformable theory (TSNDT) and the three dimensional (3D) elasticity theory. We used the commercial …

Energy Efficient Passenger Comfort in Underground Subway Environments
… It couples a 1D model of a subway line with a 3D FEM model of vertical ground heat exchangers. The 1D subway model represents spatially averaged transient heat and air flows in the underground, while the FEM model simulates vertical close-loop GHEs next to the subway tunnels. The two models are …
