Title (EN) TOPOLOGY OPTIMIZATION USING REDUCED LENGTH BOUNDARIES ON STRUCTURE SEGMENTS OF DIFFERENT THICKNESSES
(FR) OPTIMISATION DE TOPOLOGIE À L’AIDE DE LIMITES DE LONGUEUR RÉDUITE SUR DES SEGMENTS DE STRUCTURE DE DIFFÉRENTES ÉPAISSEURS
Abstract:
(EN) A method and apparatus determines an optimal design of an engineered structure formed of segments having different thicknesses. The techniques include receiving a design model for the engineered structure. The design model includes a finite element model of a spatial domain wherein the engineered structure is contained and an objective function to be optimized. Based on satisfying a converged objective function value and a lower bound of material density values, the techniques are able to produce a completed model of the engineered structure.
(FR) L’invention concerne un procédé et un appareil qui déterminent une conception optimale d’une structure d’ingénierie formée de segments ayant différentes épaisseurs. Les techniques comprennent la réception d’un modèle de conception pour la structure d’ingénierie. Le modèle de conception comprend un modèle d’éléments finis d’un domaine spatial, dans lequel la structure d’ingénierie est contenue, et une fonction objective à optimiser. Sur la base de la satisfaction d’une valeur de fonction objective ayant convergé et d'une limite inférieure de valeurs de densité de matériau, les techniques sont aptes à produire un modèle complété de la structure d’ingénierie.
