Forming Strains in ASME

The equations for calculating forming strains are available in the following tables:

  • Division 1: Table UG-79-1
  • Division 2: Table 6.1

NextGen uses for both standards the equations of Division 2, because it has more cases, including one-piece dished heads.

The result printed in the report is informative only, high forming strains may require a heat treatment on the part.

If you are designing a vessel in Division 1 and you do not need the calculation of the strains of a one-piece dished head, you can suppress the calculation by inserting a zero in the field "Blank diameter multiplier".
