Hi, so one of the designers at my company has decided to go cutting-edge and create a structure using COTS carbon fiber structural members from dragonplate.com
In particular, there are shapes like this one:

What's the upper maximum that this steel can be heat-treated to? (e.g. becomes too brittle for practical use)?
Is there a materials guide somewhere that covers this information for a broad set of steel grades?
Please advise. Thanks!
It's cards on the table time. An aggressive design schedule on a welded aluminum 6061-T6 structure has forced you into a corner [edit: in terms of getting welds to meet strength requirements]. Do you...
(A) specify 5356 filler?
(B) call out CJP welds on more than just a few places...

As a follow-up to this old thread, it's known that CBUSH elements can be used to connect surfaces with offsets (e.g. the cbush elements can have non-coincident nodes), but is there a rule of thumb on how large the gap/how long the cbush can really be? Like say for example...
On the surface, 15-5 in condition A, AMS5659 has excellent strength properties (F.tu = 160 ksi, F.ty = 140 ksi on the AK Steel website (aksteel.com), etc)
I was told by one of the older materials engineers (now retired), that one should never use 15-5 in just its annealed condition due...

I have a cover that I need to analyze for an impact load (in this case, a 1 lb object that is dropped from a height of 20 in). I have an analysis document, but the person who wrote it skipped a bunch of steps and also might be too busy to answer any questions/get involved...

Don't the threads on the insert take any amount of the external load?
I've been usually adding the preload + the full amount of external load to check and see if the parent material the...
I usually use the basic minor diameter for computing the section modulus of a bolt in bending. It's the smallest diameter, and thus conservative. But is there perhaps a way to be less conservative?
Has anybody else used the effective diameter that can be back-calculated from the stress...

Hi smart people...I also need your help. Please refer to Irene's diagram.
The spacers are 1" in diameter, with a 0.2" concentric thru hole to allow a #10-32 bolt. They are about 2" long and separate two plates as in the diagram in the referenced thread. The...
