Flexural Strengthening of Deficient Reinforced Concrete Beams with Post-Tensioned Carbon Composites using Finite Element Modelling

The application of external post-tensioned steel bars as an effective way to strengthen an existing bridge has been so far used in many different countries. In recent decades, however, they have been replaced by bars made from Carbon Fiber Reinforced Polymer (CFRP), as a material with high tensile strength and corrosion resistance, to address several concerns with steel bars such as their appli...

Anisotropic adaptive finite element method for modelling blood flow.

In this study, we present an adaptive anisotropic finite element method (FEM) and demonstrate how computational efficiency can be increased when applying the method to the simulation of blood flow in the cardiovascular system. We use the SUPG formulation for the transient 3D incompressible Navier-Stokes equations which are discretised by linear finite elements for both the pressure and the velo...

Validation of Finite Element Based Forward Approaches Using Anisotropic Volume

The excellent temporal resolution of magnetoencephalography (MEG) is universally acknowledged, but the accuracy of its source estimation is often questioned on theoretical and practical grounds. Here, we evaluate the localization accuracy of MEG for four widely used source modeling techniques (Equivalent Current Dipole (ECD), Synthetic Aperture Magnetometry (SAM), MUltiple SIgnal Classification...

A Stabilized Finite Element Scheme for the Navier-stokes Equations on Quadrilateral Anisotropic Meshes

It is well known that the classical local projection method as well as residual-based stabilization techniques, as for instance streamline upwind Petrov-Galerkin (SUPG), are optimal on isotropic meshes. Here we extend the local projection stabilization for the Navier-Stokes system to anisotropic quadrilateral meshes in two spatial dimensions. We describe the new method and prove an a priori err...
