Le mécanisme de rupture ductile le plus couramment observé est l'amorçage-croissance-coalescence de cavités. Les modèles couplés de type "plasticité poreuse" (GTN, Rousselier) sont présentés et leurs limites sont discuté...

The most commonly observed ductile fracture mechanism is void nucleation, growth and coalescence. Fully coupled "porous plasticity" models (GTN, Rousselier) are presented and their limits are discussed in relation with q...

The modeling of deviations from isotropic hardening still is a difficult task for macroscopic models, in particular for non-proportional loading paths. The alternative polycrystalline models suffer from large CPU time in...
