Finite Element Analysis (FEA) to Support CRN Applications

Finite element analysis (FEA) is a powerful tool for demonstrating code compliance in CRN applications where standard formula-based calculations are insufficient. Kopfkino provides integrated FEA and CRN registration services for complex designs.

When Is FEA Required for CRN?

• Non-standard vessel geometries not covered by ASME VIII-1 formula rules
• Nozzles with high d/D ratios or close spacing requiring detailed stress analysis
• Division 2 designs — FEA is the primary analysis method
• Fatigue design per ASME VIII Division 2 Annex 3-F
• Quick-opening closure analysis for complex locking mechanisms

ASME Division 2 FEA Methodology

Under ASME VIII Division 2 Part 5, FEA results are categorized as Primary Membrane (Pm), Primary Local Membrane (PL), Primary Bending (Pb), and Secondary (Q) stresses. Kopfkino's FEA methodology follows ASME Division 2 stress categorization rigorously.

Frequently Asked Questions

Will provincial authorities accept FEA as proof of design?

Yes. All Canadian provincial authorities accept FEA per ASME VIII Division 2 methodology. Kopfkino prepares FEA reports in the format expected by TSSA, ABSA, TSBC, and other authorities.
