BEM – BOUNDARY ELEMENTS METHOD USED AT THE STUDY OF STRESS CONCENTRATORS (CUTS-OFF) AT ROTATIONAL DISKS IN AXIAL-SYMMETRIC THERMAL REGIME PART III – EIGEN VALUES PROBLEMS AT DISKS
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.
