Rubber material

Dear STKO Team,

which physical property is given for modelling a rubber material as cushion material in piled raft foundation.

[STKO Team]

Rubber in general should be modelled with an Hyper-Elastic material if you want to analyze it under very large deformation.
But this is not the case.
I think cushion is used in composite pile-raft foundation just to redistribute the stress of the piles. So you can just use an Elastic Isotropic material

Any solid element is fine
