contact problems between two components

Hello,

I have a problem by creating a contact surface between two components.

I wanted to realize a stick contact, but only a few nodes interact, so at these nodes massive peak of stress appears.

I tried to change change the parameters, so i reduced the mesh-size and tried a friction-contact with a high coefficient between the two parts. The result was the same.

After this I changed the parameters fo Freeze and MOrient = Normal.

The result was way better, but a peak with high stress appeared at the end of the contact surface.

Moreover I tried to expand the contact surface.
You can see the results in the pictures, which I attached to this post.

Also I added the .hm and the .h3d file.

Can you tell me, where i made a mistake or how I can fix the problem?

Thank you very much in advance for your help.

Best regards

M. Herrmann
