Several models have been proposed in order to be able to predict the correct density and stress distributions on long bones. Most of them are of an empiric and/or experimental nature. A few are related to optimization techniques, in the framework of

Dans ce travail, nous presentons des resultats theoriques concernant l'optimisation d'un domaine dans une large classe de domaines perfores, analyses par des techniques d'homogeneisation. Une large classe de fonctionnelles a optimiser est consideree.

Les methodes spectrales sont bien adaptees a l'approximation numerique du champ de deplacement d'une poutre mince. En adaptant une technique introduite par M. Vogelius et J. Babuska nous montrons comment construire une base de fonctions de l'approxim

In this work we study the limit relations between a Galerkin approximation method, of the spectral type, for the three–dimensional linearized elasticity model of a multicellular beam, and the respective homogenization process. We show that the choi

In this work we obtain a generalization of Timoshenko's beam theory by applying the asymptotic expansion method to a mixed variational formulation of the three dimensional linearized elasticity model

We examine, in this paper, a class of contact problems in elastostatics concerned with the steady frictional sliding of a metallic body on a rigid foundation. On the contact surface we assume that friction is governed by a law of a nonlocal type. We

In this work we study the homogenized behaviour of a linearly elastic beam, with a multicellular cross section. Making use of homogenization techniques we give the limit behaviour of all the functions and constants showing up in a generalization of S

This paper presents the application of a topology optimization algorithm based in homogenization theory. Three examples in structural design will be solved numerically. The first two are formulated such that analytical solutions can also be developed
