Identification of In Situ Frictional Properties of Bolted Assemblies with Digital Image Correlation
Résumé
The present paper is devoted to the identification of frictional properties in bolted assemblies. It is shown that kinematic data provided by digital image correlation can be used to analyze the change of the friction coefficient with the number of cycles. Two approaches are followed. The first one is based on the displacement jump between the assembled plates, and the second one relies on displacement fields measured on the same surface.
