    Kelvin Voigt behaviour of Rubber

    Michael Kuhn

      Hello!

       

      I´d like to  simulate the Kelvin-Voigt behaviour of rubber-like materials? (shown in the image below):

      Deformation is slowly increasing under constant load, and slowly recovers after removing the load.

       

      Is it possible to model this using the ogden material model (maybe by using creep constants?).

      I´am using the ogden material model to compute the deflection of the top surface of a cylinder after talking away the load.

      Model:Applied Load vs. Time
      Resulting deflection of top surface:

      As you can see in the third image the resulting deflection of the top surface is not showing the desired behaviour.

      It seems to be instantaneous.


      thanks in advance,
      Michael
