ELEMENTS DE MACHINES II Machine elements II Maschinenelemente II

Author(s) : Debongnie, Jean-François
Description : Conception et calcul des vis et écrous (mouvements et assemblages), liaisons arbre-moyeux, paliers lisses.
Repository : ORBi (University of Liège)
Language(s) : French

Comportement élastique des articulations flexibles à col elliptique Elastic behaviour of elliptic notch hinges

Author(s) : Debongnie, Jean-François
Description : We present here amodel for the prediction of the elastic behaviour of elliptic notch hinges, including bending and shear in both planes, stretching and torsion. In a first step, an exact solution is established in the frame of the beam theory, making use of Sommerfeld's change of variable, which is ...

Un algorithme performant de calcul des erreurs de forme

Author(s) : Debongnie, Jean-François
Description : In this paper, an original algorithm for the computation of a form error is exposed, which is exceptionally fast and robust and which wholly conforms to ISO norms.

Pseudo-articulations à col parabolique Parabolic flexure hinges

Author(s) : Debongnie, Jean-François
Description : Ce rapport donne la théorie des pseudo-articulations à col parabolique. Faisant suite à des travaux antérieurs du Laboratoire de Méthodes de Fabrication, il adopte la même démarche, à savoir:1)Solution exacte; 2)Solution asymptotique; 3)Facteur correctif pour passer de la solution exacte à la soluti...

Fundamentals of finite elements

Author(s) : Debongnie, Jean-François
Description : This book presents the text of an introductory course on finite element methods. As written by a member of the Aerospace Laboratory of the University of Liège, it reflects the general philosophy of this pioneering research team.

Sur la consistance du lissage des contraintes par convolution

Author(s) : Debongnie, Jean-François
Description : This paper is devoted to the analysis of a stress-smoothing procedure by convolution. The key result is that any convolution kernel does not generally lead to accurate results, it is to say, a consistency condition has to be verified. Consistent kernels are then developed.

On the approximation of incompressible solids in the displacement method Sur l'approximation des solides incompressibles dans le cadre de la méthode des déplacements

Author(s) : Debongnie, Jean-François
Description : A mathematical analysis of the numerical approximation to incompressibility with nearly incompressible displacement finite elements is presented. It explains why, as observed by many authors, convergence to the incompressible solution is not necessarily obtained when Poisson's ration is increased up...

Predicting the fatigue notch effect from partial experimental data

Author(s) : Debongnie, Jean-François
Description : This paper is devoted to a new method of fatigue strength assessment, which is based on similarity relations and former results of the author on the gradient method.
