Homogenization and elastic-plastic transitions in random and FGM microstructures
… problem of determination of the Representative Volume Element (RVE) that corresponds to the effective properties of materials. Microstructural randomness is inherent in these materials and hence we study the scaling from Statistical Volume Element (SVE) to RVE. Using Hill condition, the RVE is …

Scale-dependent homogenization of elastic-viscoelastic random composites
… refers to the size of so-called Representative Volume Element (RVE), while d is the microstructural scale (microconstituents’ size) and Lmacro is the macroscale. In the randomly structured media, the RVE is considered to contain a sufficiently large number of micro constituents (e.g. inclusions) …

Avalanches, percolation, and stochastic damage evolution in disordered media
… relevant for mesoscales below the representative volume element (RVE) size. The overarching theme of this dissertation is modeling apparent properties of disordered systems on sub-RVE lengthscales using numerical techniques that are based on an explicit representation of the material …

Mesoscale random fields of stiffness for in-plane elasticity
… prior to the attainment of the representative volume element (RVE). Focusing on elastic moduli in particular, a micromechanical analysis based on the Hill-Mandel condition leads to the conclusion that two fields, stiffness and compliance, are required to bound the response of the material. …
