Why Young's modulus? You should be looking for strength.

yeah finding strength is also ok ... i need to just zero in on the material grade of polyurethane ........ there r 2 stages of problems 1 stage im not sure how to exactly find the most flexible material grade for this .... because a sheet of this material will be folded into cylindrical shape ( with around 4 rotations like that of a calneder ).... so the material needs to be very flexible n should not break or undergo plastic deformation when folded ....... im not sure how to simulate this condition n find the right material ......... 2 nd stage and after that the element is subjected to compressive force ( the amount of force is unknown )equal from all sides ..... so i need to also design the cylindrcal element for this fatigue strength ............ any suggestions please .......
