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.
Well, I poked around and found a COSMOS companion session about contact, and it answered my questions! Thanks Vince!
