Urethane modulus of elasticity 1

[Philrock]

I need to estimate the load imposed by stretching an unreinforced urethane belt over its pulleys. I know the Shore hardness of the urethane and the formulas relating stress, strain, elastic modulus, etc. How do I convert Shore hardness to elastic modulus?

 

[stanier]

I dont think you can. They are different properties.

Roughly speaking

Shore A E (psi)

35 168
45 256
55 460
65 830
75 1340
