16. A pseudoparabolic reaction-diffusion-mechanics system : Modeling, analysis and simulation
Abstract : In this thesis, parabolic-pseudoparabolic equations are derived coupling chemical reactions, diffusion, flow and mechanics in a heterogeneous medium using the framework of mixture theory. The weak solvability in 1-D of the obtained models is studied. READ MORE

17. Computational Multiscale Modeling of Pearlitic Steel
Abstract : The objective of this thesis is to investigate the possibilities to describe the mechanical behaviorof a pearlitic steel by using computational homogenization, or multiscale modeling. The proposed model contains three scales: the engineering macroscale, the mesoscale representing the colonies of the pearlite and the microscale containing the individual cementite lamellae and the ferrite matrix.

19. Homogenization of some elliptic equations with connections to elasticity
Abstract : In this PhD thesis we prove some properties of elliptic equations in connection with periodic homogenization. We mainly study the stationary linearized elasticity system. This thesis consists of five papers complemented with a short introduction.The first paper concerns some elliptic equations on a domain with oscillating boundary. READ MORE

20. Homogenization theory for structures of honeycomb and chessboard types
Abstract : This thesis consists of 5 papers. The first paper starts with an introduction to some of the most fundamental mathematical theory connected to homogenization. In particular, a portion of the classical theory in homogenization is presented, such as the convergence of monotone operators and homogenization in random domains. READ MORE
