Effet des fluctuations de fractions volumiques en contexte stochastique : construction d'un modèle probabiliste et stratégie de résolution

Abstract : Many materials encounter fluctuations and uncertainties on their macroscopic mechanical properties. This basically results from random fluctuations observed at a lower scale, especially at the mesoscale when microstructural uncertainties are considered. The aim of the present study is then to propose a new metholodology that allows to evaluate the impact of a randomly fluctuating volume fraction at the mesoscale of composites. In particular, the methodology of construction of the probabilistic model as well as the strategy for solving the mechanical problem are described.
