Encadrement strict et non-intrusif de quantités d'intérêt dans les calculs éléments finis en viscoélasticité linéaire

Abstract : We present an attractive method that yields strict and efficient error bounds for local quantities in linear viscoelasticity problems described through internal variables and solved by means of the Finite Element Method. It enables on the one hand to take history effects into account. On the other hand, it uses enrichment functions introduced through the Partition of Unity Method, which brings a non-intrusive feature and is appropriate to deal with error estimation on pointwise quantities of interest.
