ABSTRACT:
The present papers presents the theoretical method for the determination of the deformations and the loss of the stability of the disk stressed by an axial – symmetric thermal field, variable according to disk radius and thickness, superposed with a field of membrane tension given by the rotational motion. The experimental results confirm the theoretical hypothesis. This paper also presents the tension and deformation state of the disks being in a non – stationary field of temperature. The study is done until the plastic deformations occur.
