Normal, sheer, and strain in Spiral/Helical Rope under Axial Tension

[Jfries289]

I'm in grave need to be able to calculate normal and sheer stresses and strain on spiraled or woven structures in general, and specifically on ropes. I'm doing a comparison to the hierarchical microstructure of collagen for a biomechanics paper based around the micro and macro structure of biological systems in comparison to real world applications.

Being able to calculate ultimate tensile strength as a function of spiral/helical radius would be most useful.

Try the cable manufacturers, they have a wealth of experience and can go on for hours about various layups.
