In order to study buckling propagation mechanism in deep sea pipelines, the contact between pipeline’s inner walls in buckling process was studied A two-dimensional ring model was used to represent… To study the collapse of imperfect subsea pipelines, a 2D high-order nonlinear model is developed
- Buckle propagation in submarine pipelines - Nature
DURING its construction a submarine pipeline is at the same time bent and loaded by the external pressure of the sea If it is bent too far, it buckles If the local external pressure is
- Behavior of Buried Subsea Gas Pipeline Using Vector Form . . . - ISOPE
A special nonlinear soil spring model was developed for the VFIFE shell elements and numerical strategies were proposed to solve the multifold nonlinearities of geometric, elastoplastic material, and self-contact collision
- Buckle interaction in textured deep subsea pipelines Author
To control the non-linear FE analysis (for both textured and cylindrical pipes), a localised wrinkle imperfection ω is imposed on the compression side of the pipe at mid-span [8]
- Nonlinear Contact Between Inner Walls of Deep Sea Pipelines in Buckling . . .
A theoretical study on buckling propagation must start from the contact involving three types of nonlinear problem, namely geo-metric nonlinearity due to pipeline’s large deformation, plastic material nonlinearity in the wall area with larger strain, and contact nonlinearity between pipeline’s inner walls
- Theoretical and finite element methods for cross-section design of deep . . .
Yangyang et al (2021) investigated the nonlinear mechanical behavior of reinforced thermoplastic pipes, combining the Hashin–Yeh failure criterion and composite material damage evolution model to analyze the deformation and stress of pipes under internal pressure
- Nonlinear contact between inner walls of deep sea pipelines in buckling . . .
In order to study buckling propagation mechanism in deep sea pipelines, the contact between pipeline’s inner walls in buckling process was studied A two-dimensional ring model was used to represent the pipeline and a nonlinear spring model was adopted to simulate the contact between inner walls
- (PDF) Nonlinear contact between pipeline’s outer wall and slip-on . . .
The 3D finite element modeling of the buckle propagation is presented by considering the inertia of the pipeline and the nonlinearity introduced by the contact between its collapsing walls
