Abstract

L'invention concerne un procédé visant à obtenir une topologie optimale d'une structure sur la base d'un ensemble de critères de conception tels qu'au moins un point de support et au moins une force à appliquer à la structure. Le procédé consiste à identifier une pluralité de noeuds dans un domaine de conception de structure et affecter à la pluralité de noeuds une valeur de densité initiale. Le procédé consiste à effectuer une analyse par éléments finis sur les noeuds, déterminer pour chaque noeud une valeur d'intensité du stress, classer les noeuds par valeurs d'intensité du stress relatives et ajuster la valeur de densité pour chaque noeud. Le procédé consiste également à répéter les étapes consistant à effectuer une analyse par éléments finis sur les noeuds, déterminer la valeur d'intensité de stress pour chaque noeud, classer les noeuds par valeurs d'intensité de stress relatives et ajuster la valeur de densité pour chaque noeud jusqu'aux conditions d'arrêt, ce procédé permettant ainsi d'obtenir une topologie optimale.
