Hello everyone.

I would like to know if there is any possibility to simulate an interface(non linear) very tiny in the range of millimeters between two bodies achieving through it strain/stresses transfer(compression, shear and tension) from  one body to another.

I would glad to hear any idea.

Thank you in advance.

That would be Bonded Contact.

Thank you very much for the answer.

In the case of non linear contact in which way could I achieve this strain/stress transfer between the two bodies.

There is any possibility somehow to simulate this kind of non linear interface?

Thank you in advance.

You included tension in your list.  If you left that out and wanted sliding and separation, then you would use Frictional Contact.

If you want to study the failure of the bonded contact under tension or shear, then you can use the Cohesive Zone Model (CZM). There are several Discussions on this site for that topic.

Thank you very much for the quick response.

Is there any possibility to study non linear contact(frictional) under tension? Could this option be simulated?

Thank you in advance.

Compression implies a force pressing the two faces that contact together.

Tension implies a force that pulls the two faces apart.

If there is some adhesion at the interface, that is where the CZM with a Bonded Contact can model the peeling apart of the faces at the interface under a tensile load.

It would help if you Insert an Image of the geometry and point out the interface and which direction the forces are being applied.
