    Flexible pipe in abaqus

    Thanks for your answers. I am familiar with the orcaflex, but my analysis is complicated in later stages and orcaflex can not handle that as far as I understand. And I have no expirience with orvcaflex either. Shell elements would be nice, but my model is 350m long, so its not really an...

    Flexible pipe in abaqus

    Hi, Im trying to model a flexible pipe using beam/pipe elements in abaqus. With flexible I mean a pipe with high axial stiffness, but low bending stiffness. I know I can model a beam general section and define I11, I22, I12 separately and that way get the behavour I want. But I also need to...

    Cable inside a pipe

    The pipe and the cable are modelled with beam elements B31H (hybrid formulation). The thing is that you define the E-modulus and the beam section (in this case circular), which than decides your EI (bending) and EA (axial) stiffness. But I want the bending stiffness to be very small. Is there a...

    Cable inside a pipe

    Hi all, Im trying to make a model of an electrical cable inside a pipe laying at a seabed. This is modeles using the 'slide line option in abaqus. The pipe is subjected to temperature loading and expands. The cable can not see the same expansion; hence it has to be layed with an overlength...
