Abstract

The present paper presents the theoretical method for determination the deformations and the loss of stability of the disk stressed by an axial symmetric thermic 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.
