Full Debonding Process of Adhesively Bonded Composite and Metallic Pipe Joints under Torsion

Bonded joints are very common in many pipeline systems, in which the bond behavior of the joint interface is of crucial importance. This paper presents two analytical solutions for the debonding process of a pipe joint under torsion, assuming that the bond interface follows either an exponential sof...
