Konstruktionsbegleitende Simulation (FEM)

2017
Die Simulation von Produkten ist ein wichtiger Bestandteil in der Produktentwicklung. Durch fruhzeitige Simulation und einhergehende Optimierung von Produkten und Modellen kann eine grose Kostenersparnis erzielt werden. Mit steigender Genauigkeit der Simulationsprogramme und steigender Rechenleistung werden in der Vorserienfertigung immer weniger ...

DOMAIN DECOMPOSITION WITH BEM AND FEM

International Journal for Numerical Methods in Engineering, 1997
A method is constructed where we have coupling of the two different title methods in a weak form. As a result, we can analyse a given structure with two different grids independent of each other. On this account, we see that the advantage of the proposed method is in its ability to couple BEM and FEM. The construction of the numerical algorithm depends

Two-scale modeling of granular materials: A FEM-FEM approach

Frontiers of Structural and Civil Engineering, 2013
In the present paper, a homogenization-based two-scale FEM-FEM model is developed to simulate compactions of visco-plastic granular assemblies. The granular structure consisting of two-dimensional grains is modeled by the microscopic finite element method at the small-scale level, and the homogenized viscous assembly is analyzed by the macroscopic ...

FEM Bending

2005
The paper is concerned with the numeric procedure in plate bending. For numeric procedure the finite element method is used. Calibration force is determined when bending force and calibration coefficient are known. The calibration coefficient is determined by experiment.

Herleitung der FEM

2010
Wie im Folgenden fur das Beispiel eines Zugstabes gezeigt, lasst sich unter der Annahme sowohl geometrisch als auch physikalisch linearen Verhaltens die Finite Elemente Methode auf unterschiedlichen Wegen herleiten.

A comparison between hybrid methods: FEM-BEM versus FEM-DBCI

COMPEL: The International Journal for Computation and Mathematics in Electrical and Electronic Engineering, 2013
Purpose – The purpose of this paper is to compare the hybrid FEM-BEM and FEM-DBCI methods for the solution of open-boundary static and quasi-static electromagnetic field problems. Design/methodology/approach – After a brief review of the two methods (both coupling

FEM synthesis of electromagnetic fields

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2000
A theory of equivalent fields is studied, analogous to equivalent circuits in network theory. A complex geometry where electromagnetic field has to be studied is subdivided into subdomains; for each of them an equivalent subdomain is found, that has the same external behaviour but a minimum number of interpolatory nodes.

Grundregeln der FEM-Anwendung

1990
Im Nachgang zu den bisherigen theoretischen Darlegungen zur FE-Methode sollen abschliesend einige Grundprinzipien der Anwendung diskutiert werden, deren Nichtbeachtung entweder zu Fehlern oder unnotigem Nachbesserungsaufwand fuhrt. Da in der Praxis die Anwendungsgesichtspunkte und damit Probleme naturgemas sehr vielschichtig sind, konnen die folgenden ...
