- W2019589715 abstract "The analysis of mechanical structures using the Finite Element Method in the framework of large elastoplastic strain, needs frequent remeshing of the deformed domain during computation. Indeed, the remeshing is due to the large geometrical distortion of finite elements and the adaptation to the physical behavior of the solution. This paper gives the necessary steps to remesh a mechanical structure during large elastoplastic deformations with damage. An important part of this process is constituted by geometrical and physical error estimates. The proposed method is integrated in a computational environment using the ABAQUS/Explicit solver and the BL2D-V2 adaptive mesher. To cite this article: H. Borouchaki et al., C. R. Mecanique 330 (2002) 709–716. Le calcul des structures en grandes déformations élastoplastiques par la méthode des éléments finis nécessite de recourir à des remaillages fréquents du domaine de calcul au cours de la résolution. En effet, la fiabilité et la performance d'un tel calcul dépendent fortement de l'évolution géométrique et physique du domaine de résolution. Cet article présente les différentes étapes nécessaires au remaillage d'une structure mécanique au cours de grandes deformations plastiques avec endommagement. Une part importante de ce processus est constituée par les estimations d'erreur à caractère géométrique et physique. La méthode proposée a été intégrée dans un environnement de calcul utilisant le solveur ABAQUS/Explicit et le mailleur adaptatif BL2D-V2. Pour citer cet article : H. Borouchaki et al., C. R.
