Hi

I have a problem how to model the contact between two plates en 2D,
I need to know the conditions of contact between these plates (friction- sliding)
these plates are modeling by their midlin plan,

Thanks for yous help

Hi,

can you give us more detail about your problem? I suggest you to see the tutorial "Sliding Wedge", available in the Model Library > Structural Mechanics > Verification Models. It's a simple 2D model, having a look at it may help you!

thanks for your answer

I working on modeling of assembly of two beams, which these beams are modeled by their midplane,
so i'm looking for the conditions of contact as (sliding - friction ) in the overlap region,
in general, the law of coulom present the friction problem at the contact point, but in this type of modeling the contact point is separated in deux because the solids are presented by their midplane so the sliding is between two midplane of beams and not between tow solids, so i have not the same conditions and equations,

I don't know if you have been taking a clearer idea

If your problem is that contact occurs at the mid-plane while the beams have a finite thickness, then you can use the contact surface offset feature. That allows the surfaces to be considered “touching” when they are actually apart or overlapping by a preset amount.
