Data set of critical resolved shear stress for MgO single cristal: from the laboratory to the Earth’s lower mantle conditions of deformation

摘要: We published recently a couple of papers describing the first steps of MgO plasticity from the laboratory [1] to Earth’s lower mantle conditions of deformation [2, 3] including one especially dedicated to hydrostatic pressure effects [4]. In these papers, we developped a dislocation-based multiscale numerical approach describing critical resolved shear stresses (CRSS) of MgO single cristal regarding temperature, pressure and strain rate. Here we present a dataset which provides a clear resume of all the data inferred from the model for two characteristic dislocation densities. Data tables can easily be downloaded and used (please cite articles mentionned above).
