Hello,

Im simulating a rubber pad squeezed between two concrete layers. Im using the Morlow model (Hyperelastic material) for concrete as I got the stress strain curves for the rubber in compression.

Im modelling using hard interaction. Also tried the penalty linear and lagrange multiplier interaction.

The convergence cant be achieved though. any syggestions about why? If the material model, elemen type of interaction is wrong?

I recommend that you first try with a different material model. I can try the Neo-Hookean material model which will always be stable.
