Prykladni Problemy Mekhaniky i Matematyky| Резюме: | Possible loss of stability of a rotating circular thin disk of finite constant thickness is investigated with the help of the small parameter method. The relationship between rotational velocity and radius of the plastic zone was established. Based on the Saint-Venant yield condition a characteristic equation is obtained in a first approximation with respect to the small parameter. The values of critical angular rotational velocity are found for different parameters of the disc. |
