Fatigue under fretting conditions
Abstract eng: Presented paper deals with application of phenomenological fatigue criteria on fatigue under fretting conditions. The objective is evaluation of fretting fatigue based on phenomenological criteria calibrated with relatively small set of experiments. Numerical stress analysis using finite element method was used (as usual in engineering applications) to determine stress fields and relative slips in contact interface of specimen in experimental set up. These quantities serve as input to several fatigue criteria that are to be compared each to other and evaluated. Optical measuring system DANTEC DYNAMICS Q-450 employing digital image correlation method for displacement field evaluation was used to calibrate and verify numerical model of friction. Basic results of experiments and computations are presented to be discussed.
