Angus Ramsay on Enterfea:
Large Thermal Strains in FEA

Ok, I'll admit it - I'm excited to host a post by one and only Angus Ramsay! Before we get to the post, let me just say that I actually have a chance to work with Angus on a book for Nafems (about FEA of course). So hopefully, you will see us (along with Nick [...]

FEA Design Tips #002

Wow... it's the next week already O.o This means that it's another roundup post! I will always be a week behind on what we talk about in the Facebook group (even more reason to join it!). This is on purpose - I simply want to get all the insight and those awesome discussions that happen! This [...]

FEA Design Tips #002

Nonlinear geometry benchmark

During last week I've posted a tip in the FEA Guild about using Benchmarks. Some great pointers were in the comments, but one got my attention the most: While there is no chance that I will build such database myself, I'm pretty sure we have a chance of making one together! I will try to [...]

FEA Design Tips #001

Hey People! I've recently started posting FEA Design Insights on my LinkedIn profile as well as in the Facebook group (where some awesome discussions happen). I figured I will make a roundup with the best (and most interesting) tips here... just so they will be there where you need them! Let's start with a roundup [...]

How to Learn Finite Element Analysis?

I well remember when I started learning FEA. It was the beginning of my Ph.D. and no one told me that shell stability is highly nonlinear and that FEA will be difficult to do. I just assumed I was too stupid to understand this, and I was regularly hitting a wall with my head. Now, [...]

Plasticity, isotropic/kinematic hardening… and Boris!

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

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

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!

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!

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 [...]

Flow Chart: Do I need contact

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!

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?

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?

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 [...]

Different types of analysis in FEA: beyond linear static!

https://youtu.be/inVGiGzmii0 As promised in the video, you can get my free FEA essentials course. and free nonlinear FEA introductory course! Different types of analysis in FEA (text) Just so you know: this will take around 15 min to read. As I wrote recently this year I want to help you gain confidence in the FEA [...]

Stress singularity – an honest discussion

Arjen asked me recently about stress singularity. There are quite a few articles about this issue already (it is a common problem I think). But I want to bring something to the discussion as well : ) Stress singularity basics I'm sure you have heard about it, so I will be brief. Stress singularity is [...]

Do you need to know math behind FEA?

Recently I asked a lot of my subscribers what they think is the most difficult thing in FEA. While "interpreting results" or "too much theory in materials" appeared quite often, I also got several answers like: My biggest obstacle is actually understanding the mathematical concept behind it. Although I am really interested in the application [...]

Design for stress, strain or rigidity?

This topic was on my mind (and on my to-write list) for a very long time. Finally, I had the time to organize what I want to write about it in my head. I wonder what is your take on this matter - be sure to leave a comment below! What does it mean to [...]

Few thoughts on FEA projects

This is a very special day for me, as I just launched a first paid online course on Enterfea. It took me more than half a year to make it, so naturally, I started reflecting on that process. I realized that there are a LOT of similarities between making something like an online course and an [...]

Few thoughts on meshing

Recently I've checked what topics are the most popular on my blog and it seems meshing is in high demand ( : I also figured I will try something different as a style of writing. This post will be a list of few short ideas instead of a long article about something. Let me know [...]
