Effect of Deformation mode on Viscoelasticity
Hi Jorgen,
I would like to know whether deformation modes play a role in Viscoelasticity?
I am currently performing tyre simulations and elements inside the tyre undergoes complex deformation and therefore to capture its behaviour should I include cyclical loading data through different deformation modes?
It is not necessary to perform experimental tests in different loading modes if you plan to use a material model that is based on I1 (e.g. Arruda-Boyce, Yeoh, Neo-Hookean, Gent). This also includes linear and non-linear viscoelasticity based on these types of hyperelastic models.
If you plan to use a hyperelastic model that depends also on I2 (e.g. Mooney-Rivlin, Ogden, Extended Tube), then you should perform experiments also in different loading modes.
