interaction problem!!!

interaction problem!!!

interaction problem!!!

(OP)
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!!!

RE: interaction problem!!!

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.

RE: interaction problem!!!

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