X-FEM and FEM for Discontinuities Modelling: a Comparative Study
International Review of Mechanical Engineering (IREME), 2017In 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,

Hierarchical cascading in 2D FEM simulation of finite SAW devices with periodic block structure
IUS, 2016Application of finite element methods (FEM) to the simulation of SAW devices has been constrained by the large number of degrees-of-freedom required, resulting in large memory usage and long computation times.

Shape optimization with the Finite Element Method is a very powerful tool for minimizing stress concentration in machine components. The aim is to find shapes of domains so that the stress field at the critical boundary has a special characteristic. This is important because stress optimal machine components show a better fatigue behaviour if they are ...

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)
2017Die 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 ...

A comparison between hybrid methods: FEM-BEM versus FEM-DBCI
COMPEL: The International Journal for Computation and Mathematics in Electrical and Electronic Engineering, 2013Purpose – 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
