Revealing the competitive fatigue failure behaviour of CFRP-aluminum two-bolt, double-lap joints

The fatigue failure behaviour of CFRP-metal fastened joints in highly-loaded structures differs from that of CFRP-CFRP or metal-metal fastened joints because of the significant dissimilarity between fatigue damage mechanisms of CFRP and metal materials. In this paper, the competitive fatigue failure behaviour of a CFRP-aluminum two-bolt, double-lap joint was revealed via experiments and a novel numerical prediction method. In the proposed...
