[ What is claimed is:] [1.]1. An apparatus for passive damping of vibratory strain in a turbomachine component that experiences high steady state strain, the vibratory strain having associated with it mechanical energy, the apparatus comprising:a mechanical-to-electromagnetic energy transformer mechanically coupled to the component, said energy transformer receiving mechanical energy associated with the vibratory strain of the component and producing, from said mechanical energy, electromagnetic energy; andan electromagnetic circuit electromagnetically coupled to said energy transformer, said circuit receiving electromagnetic energy, from said energy transformer, that is then dissipated through passive damping. [23.]23. A method for passive damping of vibratory strain in a turbomachine component that experiences high steady state strain, the vibratory strain having associated with it mechanical energy, the method comprising:providing a mechanical-to-electromagnetic energy transformer mechanically coupled to the component, said energy transformer receiving mechanical energy associated with the vibratory strain of the component and producing, from said mechanical energy, electromagnetic energy; andproviding an electromagnetic circuit electromagnetically coupled to said energy transformer, said circuit receiving electromagnetic energy, from said energy transformer, that is then dissipated through passive damping.
