“…The study found that a circumferential defect has a great influence on the ultimate axial force of the pipeline. Qiao et al [29] developed analytical formulas and finite element models, and concluded that an increase in internal pressure can enhance the tensile stiffness of the hose. Bai et al [30,31] established a finite element model to study the effects of initial ellipticity, residual stress, strain hardening, yield anisotropy, loading path and other parameters on the collapse pressure of steel pipelines under combined external pressure, tensile force and bending force.…”

Affected by a complex environment, corrosion is a common defect in steel pipelines. Moreover, steel pipelines are subjected to large axial forces during their installation and operation. Corroded deep-sea steel pipelines are prone to local buckling under complex loads. Therefore, in view of this problem, the collapse response of corroded steel pipelines under the combined axial force and external pressure is analyzed in detail. First, a formula for evaluating the collapse pressure of corroded steel pipelines under external pressure and axial force is proposed. Then, the factors affecting the collapse pressure of the steel pipeline are parameterized by using the finite element method. The accuracy of the finite element model is proved by collapse tests of the corroded steel pipeline. As shown in finite element results, the diameter-to-thickness ratio, initial ovality and corrosion defect size have significant effects on the buckling response of a steel pipeline. The collapse pressure of the steel pipeline decreases as the axial force increases. Finally, based on the finite element simulation results, the parameter variables in the evaluation formula are obtained.

“…Their theoretical method, based on Knapp's cable theory [8,9], considers material nonlinearity and determines each constituent's contribution to tension resistance. Qiao et al [10] used Knapp's theory as the basis for modelling TCP under combined tension and internal pressure. Bai et al [11] developed a simplified theoretical model to investigate ovalisation of aramid/high-density polyethylene (HDPE) TCP under bending.…”

Useful characteristics of fibre-reinforced thermoplastics, including high specific strengths and moduli and excellent corrosion resistance, make them ideal candidates for offshore riser pipe applications. When in operation, risers are subjected to combined mechanical and thermal loading. In the present paper, a 3D finite element (FE) model is used to analyse stress state in a section of thermoplastic composite pipe (TCP), consisting of a fibre-reinforced thermoplastic laminate fully bonded between inner and outer thermoplastic liners, under conditions illustrative of a deepwater riser application. The effects of varying combinations of pressure and thermal differentials on the distribution of stress-based failure coefficient are examined. Failure responses under different axial tensions at low/high pressures and temperatures are assessed for configurations with different laminate ply stacking sequences. Temperature-dependent material properties are considered in the thermomechanical analysis.

“…The study in [4] considered filament-wound pipes at six different fiber angles under different types of loading: biaxial pressure, hoop pressure and tensile loading, and achieved good agreement with classical lamination theory. The combined load of tension and internal pressure subjected to reinforced thermoplastic pipes was studied in [5]. An analytical solution for design and analysis of laminated composite tubes was defined in [6].…”
