X-FEM and FEM for Discontinuities Modelling: a Comparative Study

International Review of Mechanical Engineering (IREME), 2017
In this investigation, we present a comparative study on finite elements for capturing discontinuities by means of standard finite elements (FEM) or extended finite elements (X-FEM). For this purpose, several specimens containing geometrical and material discontinuities have been analyzed. The analysis covered different basic geometrical configurations,

FEM for Plates and Shells

2003
In this chapter, finite element (FE) equations for plates and shells are developed. The procedure is to first develop FE matrices for plate elements, and the FE matrices for shell elements are then obtained by superimposing the matrices for plate elements and those for 2D solid plane stress elements.

Lineare zeitabhängige FEM

2017
Ist der Einfluss von Tragheits- oder Dampfungseffekten in der Analyse zu berucksichtigen bzw. sind zeitlich veranderliche Belastungen vorzugeben, muss das zeitabhangige Verhalten des Systems berechnet werden. Dazu sind analog zu den Impuls- und Drallbilanzen fur eine FE-Formulierung dynamische Energieprinzipien zu formulieren.

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 ...
