I am doing an analysis with a lot of "No penetration" contact. I have used a Global Friction co-efficient of 0.1 (Steel on Steel, lubricated at most places in contact). For some region in contact, i am not sure whether it is lubricated or not, hence i am not sure about giving friction co-efcient of 0.1 or higher)
Please let me know if there is any substantial variation of Stress/ displacement result with the change in Co-efficient of friction for the "No penetration" contact and behaviour of the results on decrease/increase in the Friction Co-efficient.
Thanks in advance
