A direct approach for continuous topology optimization subject to admissible loading
[Une approche directe pour l'optimisation de la topologie continue sous chargement admissible]
Comptes Rendus. Mécanique, Volume 342 (2014) no. 9, pp. 520-531.

Dans le présent article, une méthode est proposée pour l'optimisation de la topologie des milieux continues soumis à des conditions d'admissibilité statique et plastique relativement à un chargement imposé. Une propriété essentielle de la méthode est qu'en utilisant une discrétisation par éléments finis, la forme du problème d'optimisation de la topologie résultant est similaire à celle du problème direct de l'analyse limite formulé selon l'approche statique. La méthode proposée est formulée en déformations planes en utilisant un matériau de Tresca. Elle est illustrée à travers des exemples de problèmes issus de la littérature.

In the present paper, a method is proposed for topology optimization of continuum structures subject to static and plastic admissibility conditions relative to a prescribed load. A key feature of the method is that, using a finite-element discretization, the form of the resulting topology optimization problem is similar to that of the direct static approach of the limit analysis problem. The proposed method is formulated in plane strain using Tresca materials and is illustrated on example problems taken from the literature.
