The stability of axially functionally graded pipe conveying fluid is analyzed based on the
Euler–Bernoulli beam theory. The governing equation for transverse vibration is transformed …

Sandwich pipe is one of the most promising subsea pipelines for oil and gas transportation
in deep waters due to its high-strength performance and thermal insulation. The gradient of …

The failure of corroded ultra-high-strength steel (X100 and X120) pipelines under combined
axial loads and internal pressure is investigated numerically by finite element analyses, and …

The nonlinear dynamic behaviors of viscoelastic axially functionally graded material (AFG)
pipes conveying pulsating internal flow are very complex. And the dynamic behavior will …

In order to release the axial compressive force resulting from high-temperature conditions,
sleepers or distributed buoyancy sections are usually installed along the route of the subsea …

The effect of ovality length on imperfect sandwich pipes is investigated using the finite
element method in the scenario of local buckling under external pressure. First, the finite …

Sandwich pipes (SPs) with adequate strength performance and thermal insulation capacity
have become an attractive choice for oil and gas transportation in deep water. The SP has a …

The use of lined or clad pipes, which have a highly corrosion-resistant material inner layer,
is common in subsea pipelines. Unburied lined pipes may experience lateral buckling under …

This study comprehensively evaluates the thermal upheaval buckling of a functionally
graded porous (FGP) pipeline laid on an arched concave seabed. The FGP pipeline is …

The pressure shell is the most critical load-bearing component in submersible vehicles. It is
mainly used to withstand the enormous seawater pressure. In this study, a corrugated …
