see TABLE UG-79-1
if you start from flat plate Ro is infinite so Rf/Ro = 0

AN EXAMPLE
DISHED END FORMING |
|||||||||
| * Dished plate thickness | t = | 6 | mm | ||||||
| Knuckle radius | = | 150 | mm | ||||||
| Mean radius | Rf = | 150 +6/2 | = | 153 | mm | ||||
| Original center line radius | R0= | Infinity | Flat Plate | ||||||
| % Extream fiber elongation | = | ( 75 t /Rf)x(1-Rf/R0) = | (75x6/153)x(1-153/Infinity) | ||||||
| % Extream fiber elongation ( Dished end formation ) | 2.94 | < 20% | |||||||
| As per table UHA-44 max fibre elongation permitted for 304 material is 20% hence Post fabrication heat treatment is not required | |||||||||
