Experimental study of the stress gradient effect under fretting loading by full field measurement techniques
Résumé
The improvements in camera technologies and image processing have caused full field measurement techniques to become more and more frequently used in the field of experimental mechanics. Nevertheless, few applications can be found in the field of contact mechanics. Therefore, the aim of this work is to present, a novel experimental set-up based on coupled kinematic–thermal measurements used for the first time in contact mechanics. A case study of the stress gradient effect based on the crack initiation identification, of a well known 35Ni Cr Mo 16 low-alloyed steel under fretting loadings, is then presented to validate the predictions by means of this set-up.
