## Femap Bolt Preload Tutorial

I think that many engineers, especially in the structural field, start FEA to calculate complex connections. There are few traps on such problems, and one of them is preloading bolts! This is why I've created a tutorial to do just that in Femap! I hope you will like it! There are several ways in which [...]

## Fundamentals of Finite Element Analysis: Complete Beginners Guide

There is no doubt in my mind that Finite Element Analysis (FEA) is the cornerstone of my career. I attribute most of my career successes to both engineering and FEA knowledge. However, when I started, I really hated FEA... it was an intimidating thing I had to do for my Ph.D... and I almost exclusively [...]

## 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 is Meant by Degrees of Freedom in FEA?

What I really like about Finite Element Analysis (FEA) is, that it's full of small things that make you say "ah, so this is what it does!". Degrees of Freedom is just like that. It's critical to understand the very basics, but there are a few fun nuances here and there as well. Let's take [...]

## What is Buckling Analysis

I remember well when I first tried to understand buckling. For whatever reason, this was not natural for me. There were so many equations, that didn't make any sense back then! But it's way easier to understand stability thanks to FEA. To go there, we need to find a good answer to a question: what [...]

## What are the advantages of Finite Element Method

Learning how to do Finite Element Analysis took me several years. I admit I mostly learned with trial and error (there were no FEA online courses back then, or at least I haven't found any!). So if you are at the beginning of this learning process, it's natural to have doubts. It's only fair to [...]

## 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 [...]

## Can You do Finite Element Analysis by Hand?

It's the beginning of 2009. I'm sitting in one of the lectures of my Ph.D. program. Finally, we will start to learn about Finite Element Method! My company is slowly developing, and I'm really hopeful that this will allow me to spread my wings! And then professor says: "let's start with basic matrix operations"... You [...]

## 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 [...]
