Pressure Vessel Engineering is an industry leader in applying Finite Element Analysis (FEA) techniques to the design of pressurized equipment. We have run over 1,500 FEA based reports validating product safety or illustrating shortcomings. Our reports are in compliance with ASME VIII-2 and can be made to comply with the multiple different Canadian provincial registration guidelines. Our FEA capabilities include Linear Elastic Analysis, Non-Linear Elastic Plastic Analysis, Permissible Cycle Life Analysis, Buckling Failure Safety Analysis, Steady State and Transient Thermal Analysis, Flow Analysis and Frequency & Vibration Analysis.
Introduction to FEA
Finite Element Analysis in Action
Finite Element Analysis (FEA) is used in this introductory sample to iteratively refine a pressurized elbow design and provide design alternatives. Computational Fluid Dynamics (CFD) is used to choose between the alternatives.
A Step By Step Introduction to FEA
This simple manifold block is analyzed to show the steps involved in a FEA study, including quality control. A good introduction to the steps required to make sure a FEA study is done right.
FEA Articles and Samples
How Permissible Cycle Life (or Fatigue Life) is Calculated using FEA
From cycle life curves to FEA to a permissible cycle life for a vessel. How fatigue life calculations are done.
The Nuts and Bolts of Stress Linearization
Linearization separates FEA stresses into membrane and bending. Examples are provided along with sample data and a spreadsheet based stress linearization tool.
Heat Exchanger FEA with Thermal Loads Sample
The tubesheet stresses for this heat exchanger with differing tube sizes cannot be calculated by regular code rules. This FEA study combines thermal and pressure stress analysis as required by the ASME code, but FEA replaces the stress formulas that cannot function in this case. We regularly run this type of analysis on heat exchangers with non-circular tube patterns.
Sample - Seismic Analysis of a Propane Storage Sphere
This propane storage sphere is analyzed in multiple steps: 1) FEA provides the vibration frequency. 2) The building code base shear is calculated with a spreadsheet based on the FEA calculated frequency. 3) The base shear is added back into the FEA model and the stresses are compared with code allowables. A pass / fail assessment is made.
More FEA Samples
