Abstract:
An analytical model was developed using the first-order laminated anisotropic plate theory to determine the stress and strain distributions within a composite pipe joint under combined torsional and tensile loading. Taking advantage of the axisymmetric nature of torsional and tensile loads about the pipe central axis, the equilibrium equations for the three-components joint system consisting of coupling, adhesive and pipe were set up based on the displacement relation. The adhesive peel stress and shear stress were calculated using the models for 54° and 26° filament-wound pipes, and good correlations were found when comparing these results with those from finite element models.
