Pipe Stress Concentration Factor Modelling in ABAQUS
Pipe Stress Concentration Factor Modelling in ABAQUS
(OP)
For pipe modeling I need to apply stress concentration in pipe model. In ANSYS the element Pipe20 allows stress concentration in the bending, however I do not know how to model stress concentration in ABAQUS (in ABAQUS i use Pipe21 or Pipe31 element). Kindly advise.
Regards,
Amir

However, as a normal practice the pipeline is modeled by beam elements and the stiffness of concrete is usually ignored (ref to DNV-OS-F101 (Oct 2007) 5C207), and to count the SCF in the field joints it is manually calculated and then added to FEM. This has already been considered in OFFPIPE (FEM for subsea pipeline installation) and ANSYS (beam elements Pipe16 or Pipe20). However, I could not find the same in ABAQUS.
