Transport of heat from the interior of the Earth drives convection in the mantle, which involves the deformation of solid rocks over billions of years. The lower mantle of the Earth is mostly composed of iron-bearing bridgmanite MgSiO3 and approximat

The ultimate mechanical properties of MgSiO3 orthoenstatite (OEN), as characterized here by the ideal strengths, have been calculated under tensile and shear loadings using first-principles calculations. Both ideal tensile strength (ITS) and shear st

International audience; Imaging dislocation microstructures in 3D and monitoring their interactions over time is a major challenge. In this study, we show that enhancing the contrast of dislocation lines prior to reconstruction, allows to optimize an

Climb creep provides an efficient deformation mechanism for bridgmanite under lower mantle conditions.
At high pressure prevailing in the lower mantle, lattice friction opposed to dislocation glide becomes very high, as reported in recent experi

We determine the compressibility, the elasticity and the slip systems for ice X in the 100-350 GPa pressure range from first-principles calculations. Our results show that ice X has a high elastic anisotropy, which increases by more than two orders o
