Using Patran, I am experimenting with "Glueing" mismatched meshes.
Consider a 2D situation with 2 independent pairs of rectangular surfaces.
One pair (A) with a single common edge of the dissimilar length.
Method of surface generation was using a surface vector.
The other pair (B) with a common...
I am not clear what is being asked here.
It should be understood that 2024 T3 and 2024 T42 aluminum alloy has different "properties" that are stated in the two different specifications and general information about the materials. The materials 2024 T3 and 2024 T42 are dependent on the heat...
Taking the responses in turn.

If it is not obvious then I will spell it out for you.
I want to shade the background of the column cell containing the maximum value.
Other people have certainly got the idea.

I have a attached an Excel file with two columns.
Each column has a single formatting rule (shown in a graphic), where I hope what is wanted is obvious from the graphic.
I do not see the results I am expecting.
Could somebody help and explain what is going on...
Hallo aerostress82
I thank you very much for the information.
First, I have never noticed the solution that you indicate in Roarke. It is shown in edition 2 & 3 also. Theses are the earliest versions I have. When Warren C Young changed so many of the table formats in edition 5, I began to use...
Hi again
A comment to the deleted post of Burner2K.
In the past I have had to deal with a very thin curved shear panel (only) in the post elastic buckled state. Nastran SOL 105 was used.
The analysis showed that the stiffness changed at the elastic buckled state but the panel continued to...
Hi
Thanks for all comments.
I will comment on the comments in turn.

Considering the principal stress against ftu would give over optimistic results. Comparing to fbuckling (min of two values) would not be much better I think.
The situation is panel biaxial compression. The elastic...
Hi
Thanks for the input.
I have done a set of FE analysis of bi-axial stress for one panel size to see what the outcome may be.
They generate a curve which looks plausible but has no simple relationship.
I will have to look at another panel size(s) and I maybe something will gel.
It will take a...
Hi
I have been looking (text books & stress manuals I can access) to see if I could find an interaction curve dealing with a panel buckling under bi-axial compression and simultaneous shear without success.
I have seen many interaction curves, but this one I have not come across.
From what I...
Thank you all for your comments but the information I am looking for is unfortunately not mentioned.
Racooke writes of "the good material at the right heat treat condition inside".
EdStainless points out that Racookpe said "there are good reasons behind it".
I am looking for some starting...
Hi
In the Aircraft Industry it is normal practice to choose the size of an Aluminium block to be machined to be well oversize compared to the final machined part required, so that all the block outer skin/surfaces are totally removed whilst machining.
Could anyone point me in the direction of...
Hi
Many thanks for the comments/help made by all. The source "IHS Standards Store "of old versions was very helpful. Somebody else must now decide if the costs can be justified.
Yes, the question arises from trying to trace old references.
I actually started when version C was current and...
Hi
Does anybody know where older versions of MIL-5 Materials Handbook may be viewed/downloaded?
So far my Googling finds nothing older than version G.
Many thanks for any help.

Hi
Beware, MSC used to tell you that buckling analysis results should not be relied upon when using elements with offsets. I think the message is telling you that.
You do not explicitly say what versions of anything you are using but with MSC Nastran 2010 things appear to have changed. See...
From your question the problem you have is unclear.
Create a complete (this includes any appropriate applied loads) free body diagram of a single element from your F06 data (ensuring the node axes are the same analysis coordinate system) and you should see a balanced element (unless a load is...
