7. Computational Homogenization of Transient Problems - Application to Porous Media
Abstract : This thesis is devoted to the development and analysis of a homogenization-basedcomputational strategy for simulating the transient and nonlinear coupled consolidationproblem in micro-heterogeneous porous media. A variational framework and the pertinentfinite element (FE) strategy, based on a generalized macro-homogeneity condition,are proposed for the spatial homogenization of a class of transient problems, wherebythe classical assumption of first order homogenization is adopted.

8. Control Rod Homogenization in Heterogeneous Sodium-Cooled Fast Reactors
Abstract : The sodium-cooled fast reactor is one of the candidates for a sustainable nuclearreactor system. In particular, the French ASTRID project employs an axiallyheterogeneous design, proposed in the so-called CFV (low sodium effect) core, toenhance the inherent safety features of the reactor.

9. Effective properties of heterogeneous materials with applications in electromagnetics
Abstract : Composite materials, i.e, mixtures of two or more materials, are commonly used in industry, because they often have outstanding properties in comparison with the original materials. In many cases the inhomogeneities are on a very fine scale, which makes it difficult to perform a full numerical simulation of the material. READ MORE
