If you ever have tried to analyze pressure vessels, you know that there is ONE feature that you absolutely need to be able to use… Stress linearization! Why? The short answer is that you can’t extract the bending stresses and other kind of stresses you need to check your model against the ASME code section […]

## Introduction to Stress Linearization

In the finite element method, when structural elements are used in an analysis, the total stress distribution is obtained. Therefore, to produce membrane and bending stresses, the total stress distribution shall be linearized on a stress component basis and used to calculate the equivalent stresses. If shell elements (shell theory) are used, then the membrane […]

## FEA Basics – Stress Linearization explained simply

Let’s suppose that someone in a bar asks you what is stress linearization, how would you answer? (The bar just next MIT…) I would answer like that: “When you apply a pressure on a solid and this solid becomes stressed, stress created has 6 components in each point of the solid. It’s cool because your […]
