Here we report the first-principle FLAPW-GGA calculations of the elastic properties of two related layered phases, namely, the ternary arsenide SrFe 2 As 2 and the quaternary oxyarsenide LaFeAsO -basic phases for the newly discovered ''1 2 2" and ''1 1 1 1" 38-55 K superconductors. The independent e
