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 ...
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 ...
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, ...
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 ...
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 ...
MATHEMATICA notebook for computing tetrahedral finite element shape functions and matrices for the Helmholtz equation
(Institute of Electrical and Electronics Engineers (IEEE), 1998-09-01)
A MATHEMATICA notebook to compute the elements of the matrices which arise in the solution of the Helmholtz equation by the finite element method (nodal approximation) for tetrahedral elements of any approximation order ...
