Dear Shabnam,

Replace the bonded contact at G with a Fixed Joint.  Pick the hole first to put the joint coordinate system at the center of the hole. Pick the face of the screw head for the other side of the joint.

The benefit of a Joint over bonded contact is that you can easily request the total force going through the joint using a Joint Probe. In a hand calculation, evaluate the ability of the threads that have not been modeled to withstand stripping under the computed force.

Both Joint and MPC bonded contact are going to have a similar stress hot spot effect on the face of the hole. You can set the Joint behavior to Rigid or Deformable. Try it both ways. Since the threads are not modeled, it is reasonable to ignore hot spots around the hole.

Best regards,
