The interfacial behavior of pipe joints is studied in this paper. Firstly, through
nonlinear fracture mechanics, the analytical expressions of interfacial shear stress and the load-
displacement relationship at loaded end of pipe joints under torsion loads are obtained. Thus
the shear stress propagation and the debonding process of the whole interface for different bond
lengths can be predicted. Secondly, through the analytical solutions, the influences of different
bond lengths on the load-displacement curve and the ultimate load are studied. The stress trans-
fer mechanism, the interface crack propagation and the ductility behavior of the joints can be
explained.
