Simplification of FEA by Symmetry
File: NA, Last Updated: N/A, By:LB
For irregular geometry, classical B31.3 rules cannot be applied. As a result, a Finite Element Analysis (FEA) is required, meeting ASME VIII-2 guidelines as permitted by B31.3.
A special thanks to Ultraflo Corporation, #8 Trautman Ind. Dr. Ste. Genevieve, MO for allowing use of their valve geometry for this exercise.
(Note: the stress results shown do not represent actual stresses under operating conditions, arbitrary loadings were applied and arbitrary stresses are shown.)
