Structural behavior and phase stability of Uranium at high pressure and high temperature

There has been a huge effort to build up a constituent law of earthquakes involving all the processes occurring during an earthquake: such processes happen over a wide range of time and space scale sometimes overlapping, and this is why when building a numerical model, one needs to take into account that these processes can interact with each other and/or compete. The aim of this thesis is to make some steps forward in this complex scenario toward a more complete comprehension of seismic source physics.
