Apparent and effective physical properties of heterogeneous materials: Representativity of samples of two materials from food industry
TL;DR: In this paper, the authors used three-dimensional confocal images of two materials A and B from food industry made of two constituents with highly contrasted properties, having the same volume fraction but different morphologies, to estimate their effective elastic and thermal properties.

Periodic three-dimensional mesh generation for crystalline aggregates based on Voronoi tessellations
TL;DR: Numerical simulations show the efficiency of the proposed homogenization technique and the effective linear elastic properties of polycrystals consisting of grains with a cubic symmetry.

The deformation of plastically non-homogeneous materials
TL;DR: The geometrically necessary dislocations as discussed by the authors were introduced to distinguish them from the statistically storages in pure crystals during straining and are responsible for the normal 3-stage hardening.

Theory of structural transformations in solids
TL;DR: Theory of structural transformations in solids as mentioned in this paper, Theory of structural transformation of solids, and structural transformation in the solids. But, the structural transformations are not necessarily symmetric.

Determination of the size of the representative volume element for random composites: statistical and numerical approach
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.

Continuum micro-mechanics of elastoplastic polycrystals
TL;DR: In this article, the internal inhomogeneities of stress and strain in an arbitrarily deformed aggregate of elasto-plastic crystals are evaluated theoretically using a tensor constitutive law of a general kind.
