procedure for contact surfaces

[Dmaz]

hello to all I have to shape a plate that leans to a washer at a hole
the model therefore includes 2 volumes. I made two models:
la prima:I have two volumes with one shared area between the two.
Mesho and I solve, I'm actually simulating a proper bonding here?
la seconda: I have duplicated the contact areas and now the two volumes do not have shared areas but support in correspondence of two overlapping areas.
I meshato all volumes.
modelling/create contact pair/
target surface:body volume
target type: flexible
contact surface:body volume
contact element type: surface to surface

select "created symmetrical pair"deselezio includes initial penetrationI don't put on clutch coefficient.

Is this way of modeling right? I have not defined contact elements or target...
in fact seeing the tensions comes a peak where the plate goes in support.

thanks for the clarifications!

a question: Do you have to simulate a bond between the washer and plate?
ps: I use ansys classic

I'll get you an image of the analysis I have to do.
I have to simulate two configurations of this flange, the flange is connected to a plate and is pulled upward with the inclination indicated in the figure, in correspondence of the upper hole, therefore it always works in support in both cases.
in the first configuration comes into contact with the plate through two washers, in the second rests on the plate with all the internal face.
I do not have to simulate gluing, the two volumes (plate and washer) are in contact and fixed by a bolt (not present in modeling). on the inner surface of the lower holes of the plate I have bound all degrees of freedom. . I'm using classic apdl anesys, too.

Bye.

Then I understood little.

I have no experience in contacts with ansys, a little more in gluing (thanks to a couple of users of this forum including stefano garbin and wave).

At first glance I would tell you, to simulate the fact that the plate rests on the support, to use two overlapping areas on the two volumes and to couple the knots of the overlapping areas so you have to bind them.
I think! !
