    Infinitesimal Sliding

    Peter Gillespie
      I have a model that has a surface contact. When the load is applied, part A slides on part B slightly (.1" maybe) . COSMOS Surface contact is for "infinitesimal sliding". The stresses at the surface contacts are higher than expected (2-4x). The sliding is a result of an off-center load bending a beam, causing it to slide on its guide.

      My question is: What effect on the analysis is there if a surface contact slides more than an infinitesimal amount?

      I had never noticed an issue with other different models, so I thought a surface contact should work okay.
