Here, I am trying macro modeling of infilled frame in DIANA, to check whether my interface element (CSC model) between infill and frame is working or not. But stress distribution looks uniform for whole panel as shown in attached document. Can anyone please help me to find problem and solution for this.
If you say that pic looks uniformly this may be due to visualisation scale.
If you checked the stress (and strains) and they are 0, the interface elements do not work properly. Unfortunately, in the second case there are a lot of possibilities that can cause this effect.
I think Giovanni is correct. Please reduce the actual color range to a much smaller one (in the range of the blue color) and send again the photo.
Looks like some stress concentrate on corners and In most of the part of infill, stress is zero.
Some notes:
- Are you showing stresses or displacements? because I see it says TDTX and this is usually for displacements in DIANA. Sorry I am not so much familiar with FX. In diana for stresses it should show something like SXX not TDTX.
- please show the principal stresses. You are showing the stresses (or displacements) in X direction.
-The range of colors is from 0 to 5 in this moment. Can you please show from 0 to 2?
In previous picture, i plot von mises stress. Now, i plot principal stress. And i chose range 0 to 2 then some part of structure is not visible .
thats correct. Because your range is 0 to -2, if you change it to 1 to -2 you will see all the structure probably!
Wall is penetrating frame at corners. How can i solve this problem?
It is not a problem actually, if you used a zero thickness interface elements between frame and infill wall. If those elements are in compression, obviously there is wall to frame penetration, because thickness is zero but stiffness is not infinite.
