  • Poroelastic modelling of hydrogels

    Hi I am currently trying to model the indentation of various hydrogels using ABAQUS 2016.
    I read the ABAQUS documentation and evnethough my model seems to be running I still cannot observe any relaxation or creep in my model.

    The gel material properties I am using are (note that due to the size of my model I am using SI in mm, s, N)
    ** MATERIALS
    **
    *Material, name=Gel
    *Elastic
    0.26, 0.3
    *Permeability, specific=1e-05
    1e-07,0.
    I

    I provided a initial void ratio and set the pore pressure to zero on the appropriate edges so that fluid can flow out/in of the gel.

    Any help will be very much appreciated.

    I have not done any poroelastic modeling in a while ;(
