Testing and prediction of structural failures caused by fretting

Abstract

Fretting is an insidious failure difficult to predict when it will occur along the service life of a mechanical structure and to take it into consideration in the design stage. The article contains presentation of some of these failures, the analysis of causes which produce fretting fatigue and fretting wear. Testing methodology for fretting fatigue is developed but not in a full sense for fretting wear testing. The main objective of the work is the development of the testing device for fretting wear failure probability identification and analysis of the possibility to include this probability in reliability for design of the mechanical structure.
