..., including rotor flexibility and differenciating between stick and slip regions in the contact zones. The model analysis shows that depending on the motor’s operating conditions, complicated contact behavior may occur with several stick-slip subzones in each contact zone. The typical nonlinear resonance...

... problems. The rise of slip and stick regions under the punch is studied. The nonlinear equations for the unknown stick region size are obtained and solved numerically. Galin , L. A. , 1945 , “ The Punch Indentation With Friction and Adhesion ,” J. Appl. Math. Mech. 0021-8928 , 9 , pp. 413...
