Static and fatigue testing thin riveted, bonded and hybrid carbon fiber double lap joints used in aircraft structures

Experimental and finite element studies of thin bonded and hybrid carbon fibre double lap joints used in aircraft structures

“…In addition the strain energy release rate (SERR) as a function of crack length for bonded and hybrid specimens are calculated to provide better understanding on how rivets affect the fatigue resistance of joints. The FEA prediction was compared with the results obtained in the experiment conducted by the authors which was reported in an earlier publication [8].…”

“…Improper processes would result in a weak bond that is not generally possible to be detected by means of non-destructive inspection (NDI). The detrimental effect of some improper surface treatment may not even manifest in a significant reduction of the initial static strength of the bond but in an adverse impact on the durability of the adhesive bond at service temperature and moisture environment and/or under fatigue loading [8].…”

Experimental Study on the Riveted Joints in Glass Fibre Reinforced Plastics (GFRP)

“…According to the test results, one have developed damage models for the material. The research reported in the article refers to similar studies by the authors [7] and other studies [8][9][10], conducted on the GFRP and Carbon Fibre Reinforced Plastics (CFRP) composites.…”

The postbuckling behaviour of adhesively bonded stiffened panels subjected to in-plane shear loading

“…In stiffened panels, which are the basic building blocks of these structures, joints between skin and stiffeners will need to transfer more load. It is widely known that adhesive joints have several advantages over other joining techniques such as improved fatigue tolerance, potentially better crack bridging in the presence of serious damage and in many cases improved buckling stability (see Chowdhury et al [1] and Azari et al [2]). …”
