1. Micromechanical modeling using computational homogenization
Abstract : This thesis addresses micromechanical modeling of materials using computational homogenization. On this topic, theoretical and computational issues are discussed, and numerical investigations of different material systems are performed. READ MORE

2. Selected Topics in Homogenization
Abstract : The main focus of the present thesis is on the homogenization of some selected elliptic and parabolic problems. More precisely, we homogenize: non-periodic linear elliptic problems in two dimensions exhibiting a homothetic scaling property; two types of evolution-multiscale linear parabolic problems, one having two spatial and two temporal microscopic scales where the latter ones are given in terms of a two-parameter family, and one having two spatial and three temporal microscopic scales that are fixed power functions; and, finally, evolution-multiscale monotone parabolic problems with one spatial and an arbitrary number of temporal microscopic scales that are not restricted to be given in terms of power functions.

4. On computational homogenization of transient poromechanics problems
Abstract : Many engineering materials are, in fact, microscopically heterogeneous. This is true fornatural materials, such as timber and clay, as well as manmade materials, like metal alloysand concrete. READ MORE

5. G-Convergence and Homogenization of some Monotone Operators
Abstract : In this thesis we investigate some partial differential equations with respect to G-convergence and homogenization. We study a few monotone parabolic equations that contain periodic oscillations on several scales, and also some linear elliptic and parabolic problems where there are no periodicity assumptions.
