- 12. An energy storage flywheel rotor fabricated from a single body of a non-composite, non-laminated, high specific strength, brittle, isotropic solid material wherein the entire surface of said rotor comprises a layer in surface compression with maximum surface or near-surface compressive elastic strains, in directions parallel to said surface, in the range of 0.02 to 0.4%, so as to impart surface damage tolerance to the brittle body.
