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. Due to the axisymmetric nature of torsional and tensile loads about the pipe central axis, a one-dimensional model is sufficient to simulate the system response. In this developed model, a three-component joint system consisted of coupling, adhesive, and pipe was used to model different types of composite pipe joints such as adhesive-bonded socket joints, butt-and-strap joints, and heat-activated coupling joints. Good correlations were found when comparing results from both the developed model and finite element model including adhesive peel stress and shear stress distributions.
