Combining Finite Element and Boundary Element Analyses

SAE Technical Paper Series, 1986
<div class="htmlview paragraph">Two methods of combining FEA and BEA are described. The first method, called structural zooming, uses a coarse FE model to compute boundary conditions for a refined BE model of an area of interest. An automated procedure for interpolating the FEA results to obtain the BEA boundary conditions is demonstrated.< ...

Verified and validated finite element analyses of humeri

Journal of Biomechanics, 2016
Although ~200,000 emergency room visits per year in the US alone are associated with fractures of the proximal humerus, only limited studies exist on their mechanical response. We hypothesise that for the proximal humeri (a) the mechanical response can be well predicted by using inhomogeneous isotropic material properties, (b) the relation between bone

Finite Element Analyses of Repaired Articular Surfaces

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 1991
The response to a compressive load of a repaired cartilage surface, consisting of full-thickness repair tissue adjacent to normal cartilage, was predicted by the u-p finite element method and compared to that of a normal cartilage surface under the same loading conditions.

Rigid Culvert Finite Element Analyses

Journal of Geotechnical Engineering, 1986
Time-independent analyses of five of ten zones of a dummy reinforced concrete pipe at Cross Canyon are presented. All five zones are characterized by "positive projection," four in a narrow, vertical-sided trench with a projection ratio of about 0.4, one, almost fully projecting.

Finite Element Buckling and Postbuckling Analyses

Buckling and Postbuckling of Composite Structures, 1994
Abstract An overview is given of the finite element buckling and postbuckling analyses of composite plates. Discussion focuses on finite element formulations of the prebuckling, bifurcation buckling and postbuckling responses; sensitivity analysis; application of reduction methods and otherrecent computational enhancements.

Finite-Element Analyses of Flexible Pavements

Journal of Transportation Engineering, 1998
This study illustrates the usefulness of the finite-element method in the analysis of three-layer pavement systems subjected to different types of loading. The method is capable of simulating the observed responses of pavements subjected to axle loads with different tire pressures, axle loads with different configurations, and axle loads traveling at ...

Finite Elemente Analyse von Stahlbetonplatten

Beton- und Stahlbetonbau, 2014
AbstractDie Berechnung des Last‐Verformungs‐Verhaltens von Stahlbetonplatten unter Berücksichtigung der materialbedingten Nichtlinearitäten ist aufwendig und komplex. Im Rahmen dieses Fachaufsatzes werden großmaßstäbliche Plattenversuche nachgerechnet, wobei die zugrunde gelegte Werkstoffbeziehung für Stahlbeton auf dem Gerissenen Scheibenmodell [2] in

Finite Element Formulation and Analyses

1993
The rapid development of high—speed computers has facilitated the use of computational techniques in a variety of engineering applications. Today, the finite element method is one of the most popular and powerful techniques in modern engineering design and analysis of complicated structures and multi—field problems. In recent years, however, researches

Orthodontic tooth movement analysed by the Finite Element Method

Biomaterials, 1984
The position of the instantaneous centre of rotation (ICR) of a maxillary central incisor has been calculated using the Finite Element Method. It is shown that the centre of rotation is insensitive to the elastic properties of the periodontal ligament when Poisson's ratio (v) is in the range 0-0.45.

Finite-Elemente-Analyse einer Transversalflussmaschine

e & i Elektrotechnik und Informationstechnik, 2000
Es wird die Finite-Elemente-Analyse einer Transversalflussmaschine beschrieben, wobei das Hauptaugenmerk auf der moglichst effizienten Modellierung und Berechnung der verschiedenen Rotorwinkellagen liegt. Die dreidimensionalen Analysen werden mit der Superelement-Formulierung des Solvers EMAS durchgefuhrt.
