{ "title" "Elastic constants for FeNb in AFLOW crystal prototype AB3_tI8_139_a_bd at zero temperature and pressure v000" "description" "Given the zero-pressure, zero-temperature structure of FeNb in AFLOW crystal prototype AB3_tI8_139_a_bd, this Test computes the corresponding elastic constants using numerical differentiation. By default, the Hessian of the energy w.r.t. strain is used, but depending on the computed uncertainty and material symmetry violation, the Jacobian of the stress w.r.t. strain may be used instead."
