Stranded wire torsion springs
Stranded wire torsion springs
(OP)
I am trying to design a stranded wire torsion spring. Is there any information available that can be used to calculate forces and safe operating stress levels for a spring of this type?

However, when you use a strand for a helical torsion spring the strand is subjected to bending moment only therefore, I do not see the reason for using a straned wire for helical torsion spring.
Anyway, you just treat it torsion springs in patallel. For example if the strand contains 3 wires of 0.040" wire diameter. You actually have three torsion springs of 0.040" wire diameter working in parallel. So you can calculate one of them and multiply the moment by three. Just remember to use the mean (outside) diameter of the strand in the calculations.

Can you provide more info for your design problem such as available space (maximum spring diameter, maximum spring length), torque, deflection angle, type of use (static, cyclic), etc.
