Hello,

The model that I am working on is basically a long hollow tube including many small cylinders that initially in contact with the inner surface of this tube. However, these cylinders might disconnect or breakage from the tube surface when it is subjected to an external impact loading or a vibration. So, I am trying to find a contact feature that including a failure criterion between these cylindrical surfaces and the tube surface. I have found a keyword in LS-DYNA so-called “*CONTACT_TIED_SURFACE_TO_SURFACE_FAILURE” that simulate this kind of contact interface problem; however, I have to do this analysis using ABAQUS and thus I am looking for a similar keyword in ABAQUS. Any help in defining this kind of contact interface using ABAQUS, will be highly appreciated.

Thank you
