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
