Add prestrain on an hyperelastic model

Hi everyone,

I'm modelling a DEA with a PDMS (polymer) center membrane in a 2D axi-symetric model.
The membrane is prestrained to -0.2. I know want to add the neo-hookian hyperelasticity to it but the hyperelasticity overrides the linear linearity and with it the prestrain.

Has anyone got a solution to that issue?

Good evening

Vincent
