This paper deals with a nonlinear three-dimensional finite element (FE) model capable of
predicting the mechanical response of flexible pipes subjected to axisymmetric loads …

Unbonded flexible risers consist of several helical and cylindrical layers, which can undergo
large bending deformation and can be installed in different configurations to adapt to harsh …

Unbonded flexible pipes consist of multiple subcomponents which interact through frictional
contact. A full 3-D finite element analysis of unbonded flexible pipes is computationally …

Steady-state smooth surface hydrodynamic lubrications of a pocketed pad bearing, an
angularly grooved thrust bearing, and a plain journal bearing are simulated with the mass …

This paper presents an analytical formulation and a finite element analysis of the behavior of
multilayer unbonded flexible risers. The finite element model accurately incorporates all the …

This paper presents theoretical and numerical study on bending properties of unbonded
flexible risers. To capture nonlinearities in layer's sliding, the stress component due to slip …

The torsional behavior of a 4 ″flexible pipe is here studied. The pipe was subjected to
clockwise and anticlockwise torsion and also to torsion combined with tension. For pure …

In this work, the response of a 2.5 ″flexible pipe to combined and pure axisymmetric loads
is studied. A set of experimental tests was carried out and the results obtained are compared …

The fatigue damage prediction is a challenging issue in the design and maintenance
phases of unbonded flexible pipes. This arises from the necessity of conducting numerous …

The principal objective of this investigation is to develop a constitutive model to simulate the
hysteresis behaviour of unbonded flexible risers. A new constitutive model for flexible risers …
