Mixed Finite Element for Cracked Interface

Abstract: RésuméUn élément spécial basé sur le principe variationnel mixte de Reissner est présenté pour étudier la rupture interfacielle dans les bimatériaux. C'est un élément fini mixte bidimensionnel à 7 noeuds avec 5 noeuds déplacement et 2 noeuds contrainte. Cet élément assure la continuité des vecteurs déplacement et contrainte sur la partie cohérente et la discontinuité de celle-ci sur la partie fissurée. Cet élément d'interface est associé à la méthode d'extension virtuelle de fissure pour calculer le taux de re… Show more

“…Modifications were introduced to the formulation of this mixed finite element to incorporate the gradual properties of functionally graded materials. The RMQ-7 (Reissner Modified Quadrilateral), which has 7 nodes with 2 degrees of freedom per node, was developed by (Bouzerd, 1992), (Bouziane et al, 2009) configured the RMQ-7 in the natural plane (ξ, η), as depicted in Figure 3.…”
