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.
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
