you'll probably need to consider both ... why ? (we can tell you, but you'll learn better if you discover it for yourself).

seriously ? 1) be careful of electricity, for the personnel and for (maybe more importantly) the equipment. 2) if in doubt, refer to rule 1).

that I think was the same opinion of Duncan Sandy's (in 1957) ...

software developers deserve their own ring of hell

I can see some "hand wringing" over the single repair patch creating a different loadpath over the skin splice, and how some may want to repeat the fuselage testing to account for this. But I'd've thought that this additional loadpath over the fuselage splice makes it more effective (and I hear...

Opinions are like ... If I had a to patch over a splice strap, I would probably (depending on specifics blah, blah, blah ...) combine the splice strap into the repair dbr ... cut out the damage (or cancer as I'll often call it), rebuild frames and stringers, then add a large repair dblr over...

your problem is that the nodes are co-planar ... so move one node slightly off the plane defined by he other three.

I do hope you get an LPS for dredging up the exactly correct answer ...

sorry, no ... as I don't know anything about what you are doing. Is "eclipse 100" a language, like Python ? You "wrote the code" ... is this "code" a specific problem solving or a more generalised code ?? Is there no one there who can help, a thesis supervisor ?? What support do you have ...

"Mrs. KootK, who is also a structural engineer, ..." damn ! I can just imagine the dinner table discussions ! (c'mon, smile)

I assume you don't have a user manual, nor anyone who has used this s/ware ? have you run a tutorial problem ? It is obvious that you have really confused it ! A google search "eclipse 100 manual" returned a bunch of hits which looked applicable ?? YT is often a good source ...

verifying to what sort of level ? Just running s/ware isn't enough unless it's something like NASTRAN where there is a lot of knowledge and experience. Simple free FEA is IMO something to be avoided, or at least plan on doing a bunch of work validating the s/ware, and control of the s/ware...

Whilst I understand the value of load testing, I agree with Flotsam. Setting up a test would be hard enough, and then what happens if the test fails ?? And this is a low tech residential project (yes?) rather than a high tech commercial project. my 2c ... this looks pretty shite to me (but...

i was referring to this pic (from reply 19) ... ... which I read as 6.8 kN axial load in one member and 3.2kN shear in the other, so the members have bending stiffness (to support shear loads) ... and the FB looks "off" ... I see the 3.2 kN creating an unbalanced moment about the load, and...

AME ... "This is not a degree, but a licensed course focused on certifying aircraft for flight." not as I understand it ... an AME license is required for someone doing maintenance on a plane. Companies making planes (or modifying them) usually use an AME license as a "ticket through the door"...
