interaction problem!!!

[chourouk]

Hi,
On an abaqus interface I have two solids a foam and a plane, I will apply on the foam a compression so that it compresses on the interface of the plane, the problem I had was that when i applicate the compression the foam passes through the plane.
any solution please!!!

When the material stiffness is very low, then the default contact penalty stiffness is also low. Scale the penalty stiffness up or switch to direct method.

How I can stagger the rigidity of penalty upwards?

when i scale the penalty stifness up the two solids move together and there is no compression.

Attach an representative example. Otherwise it's just poking around in the dark.
