While I am still immersed endlessly iterating on a 'curved end' hammock build, a recent conversation gave me some ideas about incorporating some amount of robust stretchy fabric(ie thick spandex or neoprene) in a future design.
I can find plenty of info about calculating the stretch *percentage* of different fabrics, but given that these are mostly for clothing applications, nothing about calculating the minimal load that would cause the fabric to reach 100%, er, stretchativity. Given that in a hammock application, load handling would be dynamic and the max amount would directly correlate to the square yardage of elastic fabric involved, it would be nice to be able to find a capacity or a range - rather than buying a bunch of fabric and testing it.
For example, if you could determine the amount of static load that would cause a square yard of a particular type of spandex to stretch to say 50% capacity, that would probably be able to handle m/any load spikes.
God only knows if I'm using any of the terms correctly- my fiber design experience is pretty limited and although I've dug into tensile fabric design a bit, it's awfully complex field and as far as I can tell the textbooks are all either out of print or hundreds of dollars. I haven't found anything searching here or on the web, but maybe I don't have the right terms? I'd love it if someone could point me in the right direction. Thanksdood(s).
