Towards pure mode I loading in dissimilar adhesively bonded double cantilever beams

Nowadays, dissimilar adhesive joints are used widely in different industrial sectors. For this type of joints, the investigation of the fracture behaviour under pure mode I loading is a vital issue. In order to study mode I fracture parameters of adhesive joints, scientists have proposed standard double cantilever beam (DCB) specimens. In dissimilar DCB adhesive joints, because of material asymmetry, obtaining pure mode I is challenging. To...
