Abstract:

Accurate stress intensity solutions for multiple site damage (MSD) cracks at rivet holes in riveted joints are difficult to determine, mainly due to the geometric complexity along with the variations in rivet load transfer and rivet interference and corrosion, especially the interaction of MSD cracks.A wide riveted lap joint with MSD is modeled using a combination of explicit and spring element representations of rivets.Stress intensity factors (SIFs) solutions are obtained for different damage models.

Key words: lap , joint,  , multiple , site , damage,  , stress , intensity , factor,  , finite , element,  , corrosion , damage,  , rivet , interference
