Stuparu et alii, Frattura ed Integrità Strutturale, 36 (2016) 69-77; DOI: 10.3221/IGF-ESIS.36.08 77 thickness adherends succeed to maintain the stiffness of the assembly as compared to the aluminium joints, but their strength is diminished by the pull-out and delamination of carbon fibres. It is of great importance to rely on local deformation measurements and not on the global ones as indicated by the testing machine, which include also the deformation of the adherends. Only by using such an approach a proper understanding of adhesive failure is possible.
