Fractals in elastic-plastic transitions of random heterogeneous materials
… to study elastic-plastic transitions in random heterogeneous materials. While it is well known that many materials display fractal characteristics, very little work was done on fractals in elasto-plasticity, and so this study is one of the first attempts in that direction. Fractal …

Mesoscale random fields of stiffness for in-plane elasticity
… material properties are not possible for random heterogeneous materials at intermediate length scales, which is to say at some mesoscale above the microscale yet prior to the attainment of the representative volume element (RVE). Focusing on elastic moduli in particular, a micromechanical …

Effective mechanical Properties of material models with random heterogeneities
… and fracture strengths of material models with random heterogeneities. We start by investigating the effective elastic properties of one-, two-, and three-dimensional rectangular blocks whose Young's modulus varies spatially as a lognormal random field. We decompose the spatial fluctuations of …

Avalanches, percolation, and stochastic damage evolution in disordered media
Disordered materials are ubiquitous in nature and engineering. The physical properties of such random heterogeneous materials are strongly coupled with the strength and spatial distribution of the disorder. Disorder leads to fluctuations in material properties which become relevant for mesoscales …
