Key Elements of a Comprehensive FEA Report: A Guide to Effective Finite Element Analysis Documentation

by

As Mechanical Consulting Engineers, we often find ourselves reviewing Finite Element Analysis (FEA) reports, either for design verification or because a client is unsatisfied with a previous analysis. Unfortunately, many of these reports lack crucial information, making proper verification difficult. Here, we outline the non-negotiable sections of an effective FEA report, ensuring clarity and completeness … Read more

Designing an Expansion Bellow with Elastic-Plastic Finite Element Analysis

by

Introduction Expansion bellows are critical components in piping and heat exchanger systems, allowing for thermal expansion while minimizing stresses on connected equipment. Most bellows can be designed using hand calculations following EJMA standards, but complications arise when additional features, such as a drain piping penetration, are introduced into highly stressed areas. In this project, we … Read more

Standard Nozzle Loads

by

Nozzle loads are a crucial component in the design of petrochemical equipment and the piping attached thereto. Each nozzle will see forces in 3 directions, along with moments in 3 directions for a total of 6 loads. The magnitude of these loads can be varied infinitely between the 6 different loads for the nozzle’s structural … Read more
