Abstract
The present article investigates self-loosening of bolted assemblies under the effects of transverse loads. Firstly, we discuss the relaxation phenomenon that occurs at the end of tightening. We then perform modeling and calculus for self-loosening conditions for a short screw, neglecting the tilt of the screw in its tapping. In particular, we determine a maximum value for the friction coefficient such that this self-loosening occurs. Lastly, we indicate the procedure to confirm these results and to extend the study to the case of long screws.
