Experimental rock deformation

My PhD project is part of a broader collaborative research programme between UU and TNO. This research programme aims at advancing the fundamental understanding of rock salt creep behavior in salt production and salt cavern energy storage applications. My research focusses on experimental rock mechanics and microphysics, with the aim validate rock salt creep models and apply them on a numerical models at the field scale. I will focus on conducting experiments in order to understand the creep behaviour of rock salt, mainly under lower stresses, and other creep related phenomena that can be activated during creep, like recrystallization processes. The constitutive laws derived from the above steps will be tested against field data and eventually incorporated into TNO numerical models for rock salt. I will tackles these objectives using real-time imaging with micro-CT and deformation experiments involving natural and synthetic rock salt.
