Over 40 years of studies grain boundaries in ionic rock-salt materials have left the community divided. On one hand, numerical simulations systematically predict open, hollow structural units to be ground state. other, most recent experiments report compact structures norm. To reconcile modelling with experimental evidence, we investigate stability three high-angle symmetric tilt magnesium oxid...

This paper focuses on the presence of nodules insoluble materials within salt specimens, and their effect volumetric strain measurements dilatancy phenomenon. We analyzed experimental results over 120 conventional triaxial compression tests, found that in 20% cases, were atypical. also noted natural variability specimens can lead to a non-negligible data scattering when different are subjected ...

In the energy transition context, salt caverns are probably most promising storage solution that promotes development of intermittent renewable energies, due to their flexible and high deliverability. However, design is still challenging since it should account for entire lifetime, from rapid cycling exploitation centuries abandonment. The key an optimal a constitutive model rock ensures pertin...
