Local analysis of fretting damage by means of full field measurement
Résumé
The improvements in camera technology 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 to assess fretting damage. A well known 35Ni Cr Mo 16 low-alloyed steel was studied under various plain fretting partial slip conditions. Analysis of the thermal signal have shown the possibility of decoupling thermal effects related to intrinsic dissipation, thermoelastic sources and dissipation due to friction.
