Modelling two brazed plates

Hello everyone ,

I am meshing a cooling plate . the cooling plate basically have two plates : a) channel plate b) base plate .
Both the plates are brazed together

I have meshed base and channel plate separately .

How should i join both the plates to get real world scenario.

I have attached an image with top plate as channel plate and one base plate at bottom.
Both the plates are joined together in all region except where the channels(fluent flow path ) are there

Hi Anubhav,

You can try shell welding where the channel and base plate are joining which will represent the filler material in brazing.

Another option is node to node connectivity.

Thanks

Hi Rajashri ,
Thankyou for the response .
How to do shell welding in radioss.
Is it using the seam weld ?
If yes ,then what should be the type of weld i opt for ?

Rajashri_Saha

You can just create 2D mesh between the nodes of both parts and assign thickness (usually (T1+T2)/2).

Anubhav

You mean vertical mesh b/w nodes of both components and assign thickness to it ?

Rajashri_Saha

Yes, you can do like that.

Hi Rajashri ,
Thankyou for this suggestion,
This option will help in node to node connection in one line.
In my case i have to connect areas in both plate .

Anubhav

If I have to form a 2D mesh between both plates and join it to the elements of both plates using RBE 3.
So it will RBE3 -shell-RBE3 between both plate elements .
How can i do it in hypermesh.

In that case you can check RBE3 load transfer option available in connector. Go through the below video link on connectors and find out the suitable option for your case.
