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