hello!

 

I'm conducting structural analysis on stuff consist of several component in 2D

 

A stress contour result has discontinuity

 

I thougt this have violence on my physical intution

 

How can I get continuous contour, or is it common behavior in physical perspective?

 

I attatched stress contour.

 

All component applied bonded contact condition

 

Fixed support at left side and operating pressure applied at right side

 

Thank you

Hey,

Localized high stresses are sometimes due to contacts which might have initial penetrations. Do check the initial contact conditions properly.

It can sometimes even occur due to over constrained models or poor support conditions, if possible share some model setup info if the initial contacts are properly setup.

The mesh also seems very coarse, with highly elongated elements. Can you share some mesh info too ?

Thanks

Hello mohan!

 

thank you for applying.

 

I applying operating pressure at left holes and clamping pressure at right side of top and bottom

 

And, all component are connected with bonded condition.

 

I attatched my analysis data(It is different case with I uploaded first.

 

But, stress contour violence still remained.

I'm sorry but, I don't know how to attached my case file.

Can you know me how to do?

Hey,

We (Ansys employees) can't download files even if you are able to upload it somehow. So i would suggest to use screenshots of the setup to convey your issue. Try to include mesh, boundary conditions, contact screenshots.

Thanks

I submit mesh, boundary condition, contact condition and properties.

Thank you
