Many engineers I meet don’t know there are several failure modes… They think: « That’s pretty simple… you apply a load, the load is too heavy, so your system fails and breaks… » Ok. I acknowledge that this is obvious… systems can break under a heavy loading. In fact… even a 3 years old would understand […]

## Free Body Diagram: Why is it useful in FEA?

If you are tackling static* problems with FEA, there is a basic tool that will help you a lot: The Free Body Diagram (FBD). If you are trying to analyze static mechanisms, you probably heard this name before… But do you know what it is and how it actually works? That’s what this article is […]

## Buckling in FEA: A simple explanation and demonstration

Hundreds of engineers asked me about buckling and every time, the way that I explain it makes them understand almost immediately how it works. That’s what I’ll share with you today for the beginning of 2017 :) Buckling is very simple to understand with the simple following example. Imagine that you are pushing a parallelepipedic […]

## Safety factor: How do I calculate that?

This article talks explains the concept of safety factor and how it is calculated. It’s a fundamental notion that every mechanical engineer have to understand well. How do I know if the design of my part is « safe » enough? That’s a difficult question that many designers asked themselves. One of the potential answers involves the […]

## What is frequency response analysis in FEA

In the last article, I described in depth Modal Analysis, Eigenvalues and all what that means and in this article, I will dive into what is frequency response analysis. The most important lesson about modal analysis – Modal analysis helps to determine the modes of vibrations and the frequencies at which those modes are triggered – […]

## What is FEA modal analysis? | Learn the basics about it

Modal analysis is, along with linear static analysis, one of the 2 most common types of FE analysis. If you don’t know about those, you’ll have to review your fea basics. That’s what we’ll do here! In this short article, I’ll talk about: What is modal analysis Why it is important to know about it […]
