Wang Tiles in Numerical Homogenization Models
We present the Wang tiling concept for compression of real-world material microstructures and its application for synthesis of Representative Volume Element (RVE) in first-order numerical homogenization. We comment on reducing computational ...

Tiling concept in the RVE size determination: a step beyond Periodic Unit Cell in modelling heterogeneous materials
We present a methodology for the RVE size determination that addressed the both bottlenecks, building on the representation of microstructural geometry by means of the abstract tiling concept. Our approach generalizes the concept of...

Upscaling of coupled mechanical and mass transport discrete model
. At the microscale, heterogeneous and discrete Representative Volume Element (RVE) problem is obtained. The homogenization renders the RVE to be steady state even for transient. The mechanical RVE is solved first as it is ...

New Developments in Analytical Modeling of Mechanical Behavior of ECC
The constitutive law of ECC is obtained as the relationship between overall stress and strain of a representative volume element (RVE). The RVE is modeled as a 2-D solid element intersected by matrix cracks bridged by fibers....

Challenges of Finite Element Discretization of Wang Cubes
The paper addresses FE discretization of Wang cubes with ellipsoidal inclusions in order to allow fast and efficient assembly of RVE realizations of a material microstructure. The focus is given on satisfaction of so called generalized bound...
