TL;DR: In this article, a quantitative definition of the representative volume element (RVE) size is proposed, which can be associated with a given precision of the estimation of the overall property and the number of realizations of a given volume V of microstructure that one is able to consider.

TL;DR: In this article, the authors use a simplified homogenization polycrystal model to compute the local stress-strain fields that can be used to predict damage or crack initiation.

TL;DR: In this paper, a model able to describe local stress and strain fields in an A508 Cl3 bainitic steel was proposed to improve the quality of the prediction of resistance and life time, by taking microstructural information describing the heterogeneous character of the material and its deformation mechanisms.

TL;DR: In this article, le calcul de volumes elementaires representatifs de materiaux heterogenes permet de prevoir l'influence de la morphologie des phases and de leur repartition sur les proprietes effectives lineaires ou non, l'objectif in fine andant l'optimisation de microstructures, la methode donne acces aux valeurs locales des contraintes and deformations which permettent ensuite de previr l'apparition and la propagation de l'endomm

TL;DR: Most materials, assumed homogeneous at a specific scale are heterogeneous at lower scale as discussed by the authors, and most materials are assumed to be homogenous at specific scales are heterogenous at lower scales.
