Taux de restitution d'énergie dans un corps viscoélastique
This work deals with the development of the invariant surface integral Gθυ for the calculation of the energy release rate in linear viscoelastic mediums. On the basis of a J-integral type, the adaptation to a viscoelastic problem consists in carrying out a partition of the energy dissipated in material and the free energy only with being able to cause the crack propagation. A finite element modeling is proposed by employing an incremental algorithm allowing us a coupling of the hereditary behavior and the Gθυ calculation.
