The difference between FEM and FDM… If you are serious about FEA and you want to get deep into the theory and the method used, then you probably asked yourself this question… And you came to the right place…because this blog is about “FEA for all: From basic to Advanced” ;-) What I’ll talk about […]
Failure Modes: Understand the 5 most common failure types
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 […]
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 stress? Explanation with images
Stress Let’s start with something simple. Let’s visualize a pressure applied on an object. The pressure is causing a certain deformation to your object. After I applied the pressure, what is happening inside the object? Let’s assume the object is composed of a lot of smaller cubes. What is actually happening to one of the small […]
