Yes, that would be great. Ideally, I could review a list of materials and find one that can be wound in the smallest space balancing stiffness and the overall diameter of the material. For example, I could use acetal (delrin), PTFE, composites, etc. at smaller diameters if those materials...

I think milk jugs are usually made from Low Density PolyEthylene (LDPE) but I will take a formula that works for either one. HDPE is also commonly used in making robot parts.

Sorry, but I am not following you. Are you saying that even knowing all the characteristics of HDPE, there is no formula for calculating the minimum bending radius? Or are saying that I did not provide enough information in my question? I do see places providing the following data for HDPE...

Is there a formula to calculate the radius that a rod of a given radius can be bent around while staying in the elastic range? For example, if I had a rod that was 1/4" in diameter and made of HDPE (which I think has a modulus of elasticity of 0.8 GPa), how would I calculate the minimum radius...
