On The Development Of Finite Volume Methods For Computational Solid Mechanics
(Asociacion Argentina de Mecanica Computacional, 2007-10)
Since its initial development as a tool for structural analysis around the mid-fifties the Finite Element Method (FEM) has evolved to become the most popular and used method in modern Computational Solid Mechanics. On the ...
Shell curvature as an initial deformation: A geometrically exact finite element approach
(JOHN WILEY & SONS LTD, 2009)
An alternative approach for the analysis of arbitrarily curved shells is developed in this paper based on the idea of initial deformations. By `alternative` we mean that neither differential geometry nor the concept of ...
A general technique to embed non-uniform discontinuities into standard solid finite elements
A general technique to embed non-uniform displacement discontinuities into standard solid finite elements is presented. The technique is based on the decomposition of the kinematic fields into a component related to the ...
Adaptive non-nested multigrid methods
Analysis of mechanical behavior in bending of polymer composites using the finite elements method
The use of composite materials has increased in the recent decades, mainly in the aeronautics and automotives industries. In the present study is elaborated a computational simulation program of the bending test using the ...
Finite element analysis of anisotropic optical waveguide with arbitrary index profile
This work presents the application of a scalar finite element formulation for Ex (TE-like) modes in anisotropic planar and channel waveguides with diagonal permittivity tensor, diffused in both transversal directions. This ...
Free tools and strategies for the generation of 3D finite element meshes: Modeling of the cardiac structures
The Finite Element Method is a well-known technique, being extensively applied in different areas. Studies using the Finite Element Method (FEM) are targeted to improve cardiac ablation procedures. For such simulations, ...
Simulations of incompressible fluid flows by a least squares finite element method
In this work simulations of incompressible fluid flows have been done by a Least Squares Finite Element Method (LSFEM) using velocity-pressure-vorticity and velocity-pressure-stress formulations, named u-p-ω) and u-p-τ ...
