I have a problem with a stacked colum of elastomeric membranes (natural rubber or silicone).
I am looking for a compression buckling criterion that applies for hyperelastic materials in presence of large deformations (up to 400%).
I've read about Haringx formula, that should apply for these materials, but I suspect that it is valid for small strains only.
My question is:
- is there a suitable buckling criterion for this case?
