stress analysis fundamentals

stress analysis fundamentals

stress analysis fundamentals

(OP)
folks,
so I have been told by my seniors my fundamentals are weak.. and to an extent I agree with that.
I want to get better and increase my stress analysis fundamentals knowledge. Could you guys please advise where I can start? flabel? bruhn?
if yall have any pdfs etc.& are willing to share, I would really appreciate it.

RE: stress analysis fundamentals

Flabel is formatted more like a modern structured course, Bruhn is more like a reference book, so that suggests where you can start, from that point of view.
I am not sure what fundamentals you want to build, so just doing hand-calcs from a textbook may not be the answer.
Assuming that you mean aluminum sheet-metal and riveted/bolted connections most common in 20th-century aircraft production, have you ever driven a rivet?
Have you drilled the hole, matched it to another mating piece, torqued the bolt, and load-tested the assembly to failure?
It's amazing how many engineers haven't done that stuff.

RE: stress analysis fundamentals

What kind of structure are you typically working on? (Wing? Fuselage? Control surfaces? Interiors? Landing gear....? ) New design or modifications?

How are your free body diagram skills? How is your familiarity with typical loadpath assumptions?
E.g. try freebody-ing a wing rib. Develop a shear and bending moment plot for it. Where would you take section cuts? How would you orient the section planes? How would you correct for flanges non-orthogonal to the cut plane? What failure modes would you check on the flanges... The web? The stiffeners?

Is that the sort of guidance you're after? Or something else?

RE: stress analysis fundamentals

I've also found these books by MICHAEL CHUN-YUNG NIU to be quite informative...

Airframe structural design : practical design information and data on aircraft structures

Airframe stress analysis and sizing

Composite airframe structures : practical design information and data

RE: stress analysis fundamentals

I'd start with your school/college/university texts, like for "Strength of Materials"

another day in paradise, or is paradise one day closer ?

RE: stress analysis fundamentals

You were told that your fundamentals are weak.

Your plan is to strengthen your stress analysis fundamentals knowledge.

Are you sure your plan is aligned with what your seniors are telling you?

RE: stress analysis fundamentals

Also an odd question: do You get excited about aero stress analysis... or is it just a job?

RE: stress analysis fundamentals

Probably realized all he/she/ze was going to get was a lengthy list of rhetorical questions, or a printout from an IHS subscription.
