This thesis falls under an approach of investigation on the damage mechanisms of high zirconia fused-cast refractories. The focus is particularly set on the...

In this thesis, I studied the impact of grain size on the rheology of the mantle of the Earth. We propose a new model of grain size evolution and show that the...

The aim of this work is to study the nano-scale deformation mechanisms within the spherulitic structure of semi-crystalline polymers. The deformation mechanisms are...

In order to design reliable concrete structures, prediction of long term behaviour of concrete is important. In fact, creep deformation can cause mechanical...
