I just need to add, in my handcalc's I calculated the bending stress and shear stress at the root of key boss shown in picture. and the max. stress in FEA is in conact edge of two components. and von mises stress at that point has been calculated.
As a question, is a static analysis is correct...
Hi guys,
Thanks for your comments, But still I'm confused. These day I've seen different documents and procedure, but i could not the answer of my question.
So I just decided to ask my question as simple as possible and show that as an example.
please have a look at the picture attached to this...
Hi there,
I found a nice procedure for stress analysis in a standard AS1210. This standard is a pressure vessle design code and I just wondered if it is applicable for general purpose stress analysis?
Based on that, the stress is categorized in 5 groups as follows:
1- General primary membrane...
Rb1957, Corus,
Thanks for your comments,
Let me ask my question in another way. I like to know how I should report the result of FEA in accordance with a specific codes.
Is that right that I define a permissable von misses stress based on the standard, for example:
Sn = 0.6 SY
t = 0.45 SY
then...
Thanks all friends, your comments has been usefull.
As another question in this subject; I like to know how we can connect the result of FEA with the permissable stress nominated in the codes and standards. For example, in the standard I'm using, has been mentioned:
For combination of tension...
Ed.R, thanks for ur comments.
I like to know what will happen in real situation. At that area the stress is high, two peices of the part is welded.
I found that in real situation, there are some plastic deformation in a such area with high stress and after that the stress will be released. But...
RB1957, thanks for ur comment.
I couldn't understand what you mean about real model. That's the CAD model of the part has been design and the bevelled edge are the weld and meshed as solid.
Could u please explain more about the proper model for FEA.
Cheers
Thanks all for answering.
I've attached a picture of that situation I explained.
In this case, at the corner of welded edges, the stress is about twice of the permissable stress (based on the standard). The material is 6061 - T6.
Could you please give me some idea about this matter...
Hi there,
I got a question and I really appreciate if someone could give me some idea. Thanks in advanced ;-)
My questio is about evaluate of FEA result of structures. Infact, there are some localized high stress area in the FEA result, for instance, at the filet welded area of two perpendicular...
