ABSTRACT
ABSTRACT: Adhesively bonded pipe are extensively used in pipe system and pipeline failure under torsional loading is one of the most common failure modes. Owing to the complication of theoretical analysis, development of numerical method for optimized design and stress analysis of a strong joint remains a pressing issue. In this paper, a realistic bilinear local bond-slip law is employed for analyzing the behavior of adhesively bonded pipe joints under torsion, based on a parameters study by ANSYS finite element software. Several parameters (i.e. the shear modulus of pipe coupler) are considered for assessing shear stress distribution in the adhesive and loaddisplacement relationship of the interface. Finally, the factors influencing the interfacial behavior is analyzed.
