We have proposed a way of the investigation of the possible loss of stability by a rotating thin circular disk by the method of small parameter on the basis of Saint-Venant's yield condition. We have obtained a characteristic equation for the critical radius of the plastic zone as the second approximation. We also have found the critical angular rotational velocity.
