Abstract
The equilibrium of hexagonal mesh netting is calculated by a finite element method.
A triangular element has been devolopped for such hexagonal meshes[1] [2].
The hexagonal mesh is made of three families of twines. The basic hypothesis
of the triangular element imposes that the three families of twines be parallel inside the element.
The twine tension are calculated to deduce the forces on the vertex of the triangular element.
Résumé
L'équilibre de filets à mailles hexagonales est calculé par une méthode
aux éléments finis.
Pour cela un élément fini triangulaire dédié au filet à maille
hexagonale a été développé [1] [2]. La maille hexagonale est
constituée de trois familles de fils. L'hypothèse de base de l'élément triangulaire
impose que les trois familles de fils soient parallèles à l'intérieur de l'élément.
Les tensions dans les fils sont calculées pour en déduire les efforts aux sommets
de l'élément triangulaire.

| What is OpenURL? |
- If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
- You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
- You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
