Ab initio study of the elastic behavior of MgSiO3 ilmenite at high pressure [PDF]
, 1999 We investigate the athermal high pressure behavior of the elastic properties of MgSiO3 ilmenite up to 30 GPa using the ab initio pseudopotential method. Our results at zero pressure are in good agreement with single-crystal elasticity measurements.
