Pressure Vessel FEA: Insights for Beginners

Considering using Finite Element Analysis (FEA) to evaluate pressure vessels? It's a complex and specialized field, but with the right guidance, you can gain valuable insights into their performance. This blog post delves into key considerations for beginners:


FEA for pressure vessels is complex: While you might be familiar with FEA and design rules, using it for pressure vessels governed by ASME codes requires specialized knowledge and experience. Underestimating the complexity can lead to errors and safety risks.


Essential qualifications:

  • FEA expertise: Understand the method, its limitations, and factors affecting accuracy.

  • Software proficiency: Be well-versed in the specific FEA software you'll use to avoid errors in defining parameters.

  • Code expertise: Possess thorough knowledge of the Design by Analysis methods in ASME Section VIII, Division 2, including their requirements, limitations, and reasoning behind them.

Actionable steps:

  • Seek guidance: If you lack experience, collaborate with an engineer experienced in FEA for pressure vessels to avoid mistakes and ensure code compliance.

  • Self-educate: Acquire a basic understanding of FEA, focusing on potential sources of inaccuracy like load application, mesh density, and singularities.

  • Consider ASME training: Take a course specifically covering the Design by Analysis methods in Section VIII, Division 2 to gain deeper understanding and application skills.

  • Invest in software training: Learn the FEA software you'll use through introductory and potentially specialized classes to avoid common pitfalls.

  • Consult an expert: Even with training, consider hiring a consultant with pressure vessel FEA expertise to guide you, answer questions, and review your work, especially initially.

Remember: Safety is paramount. Using FEA for pressure vessels requires specialized knowledge and experience. If you lack it, prioritize proper training, collaboration with experts, and consultant guidance to ensure accurate and safe evaluations.
