Abstract

La présente invention concerne un procédé pour la modélisation d’élément à point de Cosserat (CPE) de matériaux élastiques non linéaires, à l’aide d’une fonction d’énergie de déformation caractérisant la réponse d’un élément de brique en 3D à huit nœuds à des déformations homogènes et hétérogènes, qui comprend le couplage complet de modes de déformation en courbure et en torsion. Le procédé comprend la détermination des coefficients constitutifs qui satisfont aux modes de déformation en courbure et en torsion pour trois géométries élémentaires de référence spécifiques et la combinaison de ces solutions pour obtenir des équations constitutives pour des formes élémentaires de référence générales qui garantissent que l’énergie de déformation reste une fonction définie positive pour toutes les déformations hétérogènes du CPE. Les coefficients constitutifs caractérisent un modèle CPE généralisé qui prédit la réponse d’un élément de briques en 3D pour des déformations élastiques finies qui est dépourvue d’instabilités en sablier et de blocage pour des matériaux pratiquement incompressibles, donnant ainsi un puissant outil de modélisation.
