Glued Contact in Patran

Glued Contact in Patran

Glued Contact in Patran

(OP)
I find myself in a position where I have to run a nonlinear solid element fem.  I need to refine a portion of the model and choose to "glue" the two contact bodies.  Does anyone know how to specify this in patran 2007.  I'm running solution 600.

Note:  this model has another set of bodies with normal contact.  

 

RE: Glued Contact in Patran

maybe springs ?  very stiff in compression, as stiff as you want in tension ??

RE: Glued Contact in Patran

Kwan,

After defining your deformable bodies,

You go to Analysis>Subcase>Subcase Parameters > Contact TAble

There you can toggle the table which by default is at T (touching), you turn it to G (Glued). You might want to check the stress-free initial as well. This will avoid as much as possible the creation of high peak stress caused by the initial contact.

Make sure your contact tolerance will be able to detect your two contact surfaces.

Ask for Contact Status in the output request to make sure the contact occurs.  

RE: Glued Contact in Patran

The picture you sent is for sol106 which is the non-linear static.

In Analysis>Solution Type, choose Implicit non-linear. This will run marc in the background instead of Nastran. You should now have the contact table in the subcase parameter.

Thanks Flambter!  I got it now.  Thanks for the advice and help.
