How to learn Finite Element Analysis?

June 19th, 2018|

This is a topic I get asked about quite often. Usually, it is phrased more like "where to start?" or "what is important to know". All in all, however, All those questions can be gathered into one coherent problem. How should you learn FEA! At the start, I feel obliged to point out that I [...]

Plasticity, isotropic/kinematic hardening… and Boris!

June 9th, 2018|

Hey you all! This is something special - first time on my blog I have a post done by someone else! Do you recall that Boris Jakimov made it to the hall of fame in the snap-through challenge? We talked a bit afterwards, and this is the result! I won't edit Boris work*... but I will [...]

How to approach a snap-through problem

June 2nd, 2018|

Today's post is a video : ) In it, I will discuss various approaches to snap through problems with nonlinear FEA analysis. Understanding this was a stepping stone in my career. I really hope it will be just as useful for you! https://www.youtube.com/watch?v=GA9MyT7ax_k Takeaway: Let's sum up what I talked about: What is steering? When you [...]

Verify FEA outcomes: #FEAChecklist

May 28th, 2018|

Finally comes the time when your analysis converges, and you have the outcomes. As great as it feels, especially if there were convergence issues, now you have to deal with results! However, this is not the end of fun! In the end, you need to see if your analysis results make any sense at all! [...]

FEA analysis won’t run? Fix it with this #FEAchecklist!

May 13th, 2018|

It's time for the second part of the #FEAchecklist! Last time we were checking stuff before starting an analysis. Now, let's wonder what to check if you see analysis errors when your analysis fails to run. I can honestly say I'm kind of an expert here... I'm pretty certain I've made most of the possible [...]

Before you run an analysis: #FEAchecklist!

May 7th, 2018|

My friend and employee Asia just started a maternity leave. Since she was also responsible for training our new team member, in her "casual-self" brilliance she left her an "FEA with no stress" checklist. I've read it, and it's so awesome that I simply have to share it with you! It also gives me a [...]

Time to learn FEA

April 30th, 2018|

If I would have to name a number one issue people have with learning FEA, lack of time is definitely it. Being an engineer usually calls for a lot of work during a week, so every other minute is precious. But there are a lot of myths about learning, and especially learning FEA that I [...]

Fun story of the Hooke’s law

April 15th, 2018|

I must confess I always felt like a rebel when it comes to how I think about engineering and teaching. I'm not a complex math junky, but I don't think it stopped me to understand complex problems. If anything I believe I understand them even better... and lack of "math" simply made stuff more fun and [...]

Flow Chart: Do I need contact

April 12th, 2018|

Download the printer-friendly version here, and read the user guide below! We will tackle contact here. If you haven't read my posts on nonlinear supports and how to avoid contact you may find them interesting : ) This is not the first flowchart that I posted here. You can also check flow charts for nonlinear [...]

Choosing FEA software and good options you want to have in it!

March 20th, 2018|

A few days ago Josh sent me an email with a question about choosing FEA software. And I realized I've never actually written about it. Time to fix it I guess : ) But since I'm experimenting with videos (let me know what you think!) I've made this one about it: https://www.youtube.com/watch?v=Gq0YFTQuVL8 There are different [...]

Flow Chart: Do I need nonlinear material?

March 8th, 2018|

Download the printer-friendly version here, and read the user guide below! Last time I've shown you the way to answer a question: do I need nonlinear geometry? Today we will tackle nonlinear material. In the beginning, I need to confess, that I do mostly FEA about steel and other metals. This means that some nonlinear [...]

Flow Chart: Do I need nonlinear geometry?

February 6th, 2018|

Download the printer-friendly version here, and read the user guide below! I've already written a post on ignoring nonlinear geometry. This time I want to go way deeper into the subject. In the end, I want to create for you a simple Nonlinear Flow Chart that will help you to decide whether you need any [...]
