This work was included in the DAMREG project and financed by the European Research Council (ERC). It focuses on the incidence of the glass composition and atomic network structure on the mechanical properties, and specifically on the cracking and fracture behavior. This PhD focused on studying the mechanical behavior of dielectric glasses and was articulated around three axes. - To identify, synthesize and characterize glasses with high dielectric properties - To study and optimize the mechanical properties of the chosen glasses - To understand the potential effect of an electric field on glasses Several glasses from the BaO–TiO2–SiO2 ternary system were synthesized. Their thermal (DTA), electric (Impedance Spectroscopy) and mechanical (Ultrasonic echography, indentation, SEPB) properties were studied as well as their elastic (Resonance frequency) and viscous behavior (parallel plate viscometer) around the glass transition temperature. It was discovered that TiO2 drastically improves their mechanical properties and their temperature sensitiveness. Structural analysis (Raman, UV-Visible spectroscopy) allowed for a better understanding of the role of titanium within the glass network. Titanium can indeed be 5 and 6-fold coordinated which has a dramatic influence on the mechanical properties. Thermal treatment and UltraSonic Treatment were used to produce oriented fresnoite crystallites growing from the surface. The kinetic of the crystallization was studied by means of DTA measurements, XRD, SEM and elastic measurements. The crystallized transparent glass showed interesting mechanical properties which were studied with indentation and flexion tests. XRD measurements were also used to follow and quantify the orientation of the crystallites. Finally, the effect of an electric field on the glass viscosity and elastic behavior were observed and quantified. It was shown that an intense voltage can be responsible for a dramatic flow of the glass due to Joule heating.

Atomic Energy and Alternative Energies Commission (CEA), Tools for minor actinid nuclear pellets production development laboratory. This study highlighted the finite element modeling of nuclear fuel compaction to optimize and to predict the pressing cycle of a manufacturing press. During die pressing, a modification in the sequence of the punch displacement induced fluctuation of the axial distribution of frictional forces. Thus, the pressing cycle had an influence on the shape of sintered pellet through this axial distribution of green density. This study highlighted the finite element modeling of nuclear fuel compaction to optimize and to predict the pressing cycle of a manufacturing press (Fig.5). During die pressing, a modification in the sequence of the punch displacement induced fluctuation of the axial distribution of frictional forces. Thus, the pressing cycle had an influence on the shape of sintered pellet through this axial distribution of green density. Furthermore, the recent development of new powders with better flow behavior has influenced the design of pressing cycles. Specific powder characterizations were performed to provide the mechanical parameters of the compaction model. Finite Element Modelling of the cold compaction stage was applied to simulate the die pressing stage of alumina and cerium powders, to predict the green density distribution. The shape of the sintered pellet resulting from the non-uniform shrinkage of the green compact can also be calculated with the Abaqus code. The study showed that the double effect cycle reduces the difference between minimum and maximum diameters of sintered pellets. A correlation exists between this gap and the friction index, with a low friction index implying a low diameter difference between the top and the bottom of the pellet. The pressing cycle can then be perfectly mastered with synchronization between the stop of the die and the upper punch.
