Abstract
The present paper presents the theoretical method for determination of the deformations and the loss of stability of the disk stressed by an axial - symmetric thermal field, variable according to disk radius and thickness, superposed with a field of membrane tensions 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.
