Wow cool article, didn’t know “fastener engineering” was a defined field. Was looking up snap buttons for canvas applications earlier (for boats etc) and there were more types than I was aware of. Buttons and rivets are rather cumbersome/manual to set but certainly have their advantages.

Glue is another area that I'm sure has more than one specialty involved. There are so many types of glue and factors like heat, flexibility, hardness, heat sensitive application, uv light drying, color, texture, time to dry, catalyst drying, and a million different types of materials that might need to be glued to another different type of material.

  Obligatory reference to http://thistothat.com/ http://thistothat.com/. It doesn't cover every factor, but if you just want to quickly find an adhesive that will do a good job holding one thing to another, it's great. It also gives decent toxicity warnings.

    That is a cool site. But it is really lacking in regards to plastic (and they do seem to acknowledge that). I would love to see an expansion of the site to include various different types of plastic.

  I use a simple formula: epoxy if I need strength, CA glue with activator for everything else. (oh and wood glue for woodworking projects)

  Gluing in space applications is one of the very few areas I would consider myself close to an expert in (assuming I am not at the Peak of Mt. Stupid). As you say, the number of factors involved is really crazy, especially when it comes to proving the suitability for a new glue. Thankfully there are a relatively small number of generally applicable glues that are used for 90% of situations. For thos interested, the most commonly used glue in space in Europe is Scotchweld EC2216.

If you regularly practice the subject in the real world, ie glue stuff to other stuff, you should quickly notice whether your expertise is real?

      Thats the hope alright. So far so good on that front. Haven't had anything fall off that wasn't meant to just yet! but there is a whole world out there of glues that I havent got to work with yet, so expert still seems a bit rich to lay claim to.

        Imposter syndrome is real. But I think at some point we have to drop our false modesty and admit that we are the authorities on some things, even if our knowledge is still painfully limited.

  yeah, when I started utility woodworking i.e making a bed my old boss who dabbles in woodworking as a hobby told me forget nails. wood glue has more strength.

    Yes seriously, it’s usually the wood that will split/break before the glue

  Also the oldie-but-goodie, NASA Fastener Design Manual [1]. Rivnuts are on page 32, but not a lot of space is spent on them - they aren't strong enough for your rockets and satellites, although the military is willing to consider other types of blind rivets (page 94). Rivnuts look great to me, though! [1] https://ntrs.nasa.gov/api/citations/19900009424/downloads/19900009424.pdf https://ntrs.nasa.gov/api/citations/19900009424/downloads/19...
