How to Tackle Nonlinear Finite Element Analysis

There is no doubt in my mind, that mastering Nonlinear Finite Element Analysis was the biggest stepping stone of my career so far. It's mind-boggling how much one can do and design when using such tools. But I also remember when I started in FEA, how frustrating learning is, and how difficult it is to [...]

How to perform electromagnetic FEA

I often learn stuff when I write on the blog, as it forces me to rethink what I already know. This time, however, it's completely different! I invited a friend of mine to teach me (and you) how to perform electromagnetic FEA! This will be super fun, because in Anttis words: Electromagnetic FEA is performed exactly [...]

Difference Between Implicit vs Explicit Analysis

Picture this: You are making a presentation of your Ph.D. thesis on stability at one of the seminars. Everything goes smoothly, and finally, it's question time! And someone out of the blue asks: "what is the difference between implicit and explicit approach?"! And since you are doing static stability... you never even heard those terms! [...]

The difference between static and dynamic analysis

When I was doing my first civil engineering design I hardly thought about dynamics. Static analysis was "all there was" for me. And to some degree, it might have been even justified back then. Now, when I understand a bit more, I would like to take you on a trip! We will learn about the [...]

What are the Applications of Finite Element Analysis

I think that I have a tendency to overuse FEA. Since I know how to do it, it feels natural for me to do so! I guess it's true that when you have the hammer, everything looks like a nail to you! Thinking about this, in this post I want to discuss what are the [...]

Difference between linear and nonlinear elastic material

A few years ago I wrote an article about various nonlinear material models. Since I'm a civil engineer to me the obvious dividing line was: linear = no yielding, nonlinear = yielding. But of course, there is far more than that! Today let's take a look at a nonlinear elastic material. Both linear and nonlinear [...]

Why is a Triangular Element Stiffer?

Somehow I never used triangular elements. Not that I knew why TRI are "bad". I think I just didn't like how they look (!). This saved me quite some trouble, proving that sometimes having luck (let's call this a gut feeling shall we?) really helps! But you don't have to rely on a gut feeling - [...]

The Difference Between Linear and Nonlinear FEA?

I remember my first presentation regarding my Ph.D. It was my first year on the doctoral program, and I was starting to be on a first-name basis with people that were my teachers just a semester ago. I went to the middle of the room and started talking about shell buckling... the problem was everything [...]

How Accurate is Finite Element Analysis?

FEA accuracy is a topic that often provokes discussions. Without a doubt, there are FEA evangelists (I would include myself to the group!) and FEA disbelievers. So, let's take a look and wonder how accurate is Finite Element Analysis. FEA is almost like a calculator: it's as accurate as its user. But it's also quite [...]

How to Interpret FEA Results?

Interpreting analysis outcomes is not simple. Even if you already have proper values from your FEA analysis, still you need to decide how to interpret FEA results. Let's take a closer look at how to approach this task! Firstly let's wonder how to interpret FEA results? In structural design, you have to perform several checks. Firstly, [...]

What Are Different Boundary Conditions In FEA?

It's relatively easy to perform an FEA analysis, but it's definitely difficult to run an analysis that produces reasonable outcomes. During my Ph.D. research, I've learned that boundary conditions are often the issue. Seemingly simple they can cause a lot of trouble for you - so let's wonder what are the proper boundary conditions in [...]
