simulate constraint

[Hope]

Good morning to all.. .
I find myself having to simulate statically and dynamically a bolted plate.
the bolted plate will be pressed against studs.
What is the most correct way to simulate such a condition?
to frame the side surfaces of the holes ? to frame the plating surfaces in contact with the studs through "imprinting"? (although in reality the bare bond is unilateral).
I could also insert the part where the plate will be screwed and simulate the "glued" contact, but if you want to consider only the plate as I do?

thanks to all

Hi.
If I could post an image of the axieme would be better,
So I don't understand what your problem is.

Hello, I would like to simulate the behaviour of the embossed plate on the rectangular plate without inserting the latter (rentangle) into the fem model.
So I wondered how to simulate the fixing at the level of constraints (because the preload bolt is discounted).
will I go to bind the areas of the plate (bottles) that will actually beat on the rectangular support? or am I simply going to frame the inner surfaces of the holes of the plate to l?
I hope I've explained better

greetings

kind of hope

I think it depends on the loads that are at stake. in the presence of loads
tangential a glue contact is valid until it is exceeded
the transmissible force for friction. may be necessary to evaluate
bullion precarious for example. You could provide a more detailed explanation
of the problem.

Thank you and welcome

Well,
between your two hypotheses I would use that of imprinting by applying a fixed bond on them, then aposteriori verify that the binding reaction does not exceed the bolt/plate slip force.
It is obvious that it is not a realistic condition as you do not take into account the elasticity of the bolts, but given the thicknesses in play it does not seem to me that you can make big mistakes.
for static analysis I don't think you'll have big shocks from the truth, maybe a little more in dynamics but here depends a lot on the frequency range that interests you.
