In particular, the combination of compositematerials, such as rivets, welds, non-conformity of traditional methods have been made use of bonding joints.The fracture behavior of the adhesive is important in adhesively bonded. In the present study, the fracturebehavior of the adhesive was investigated experimentally under Mode-I loading of Double Cantilever Beam(DCB) joints obtained by using materials of different width and thickness. AA2024-T3 aluminum is used asthe adherend and two component Araldite 2015 tough adhesive is used as adhesive. The fracture progressionduring the experiment was measured with a high-speed camera and the displacement was measured by a videoextensometer. As a result; when the fracture energies of the experimentally obtained adhesive are examined,the fracture energy of the joint changes when the width and thickness of the adherend changes. In addition, thefracture energies of the joint obtained with the Corrected Beam Theory (CBT) and the Standard Test Method(SBT) are compared, and the fracture energy obtained with CBT is more accurate considering the elastic rotationin the adherend.trinfo:eu-repo/semantics/openAccessMühendislikMakineMalzeme BilimleriÖzellik ve TestArticle
