tendency to reduce by increasing  .  xy stresses are mostly uniform along the adhesive, although presenting minor peak values at the adhesive edges that also tend to reduce for higher  . Higher adhesive stiffness led to higher stress gradients. The failure analysis revealed a cohesive failure of the adhesive layer for most joint configurations, except for  =3.43º and the AV138 and 2015 due to the higher loads involved. PEEQ and SDEG analyses gave a better insight into the failure process. The P m analysis showed increasing tensile strength by reducing  , and best results for the AV138 due to the highest strength between three tested adhesives. Under the studied TSJ configuration, in which stresses are nearly uniform, it was found that the adhesive strength is preponderant over ductility, unlike happens for example in SLJ. Thus, string but brittle adhesives are recommended over less strong but ductile adhesives. References Adams, R. D. (2005). Adhesive bonding: science, technology and applications.
