… Reviewing Friction Related Results If frictional contact is present, additional contact output is available Contact Frictional Stress and Contact Sliding Distance can be reviewed to get a better understanding of frictional effects For Contact Status, “Sticking” vs. “Sliding” results differentiate which contacting areas are moving Please refer to your Workshop Supplement for instructions on: W4B-Contact with Friction H. Workshop – Contact with Friction ANSYS Details: The ANSYS options for contact types: The “Adjusted to Touch” option for “Interface Treatment” automatically changes KEYOPT(5) and KEYOPT(9) for rough, frictionless, and frictional contact. If the coefficient of friction ? 0.2, the initial substeps are set to 5 since friction is a path-dependent phenomenon. If multiple types of contact are present, the FKN, NSUBST, and NEQIT settings are set to be consistent with the most ‘advanced’ contact behavior present For example, if bonded and frictional contact are present in the same model, then frictional contact settings for FKN, NSUBST, and NEQIT will be used.
