Construction de représentations stochastiques par la Théorie de l'Information: application à la modélisation du tenseur d'élasticité apparent pour les microstructures aléatoires

Abstract : This work is devoted to the construction of a probabilistic model for the apparent elasticity tensor random eld associated with random microstructures, for which the scale separation that is typically assumed in stochastic homogenization theories, cannot be stated. The construction relies on the use of information theory and is performed having recourse to the Maximum Entropy principle. The approach is exempli ed considering an experimental database for a polycrystalline material.
