Loss of Stability of a Rotating Elastoplastic Radially Inhomogeneous Multidiameter Annular Disk

Аннотация

We propose a procedure for the investigation of the possible loss of stability by a rotating elastoplastic radially inhomogeneous multidiameter annular disk by the method of small parameter. The characteristic equation for the critical radius of the plastic zone is obtained in the first approximation. The values of critical angular velocity of rotation are numerically determined for various parameters of the disk.
