Are you able to tell me right off the bat what are the characteristics of the materials described by those stress-strain curves?
I know that it took me a long time before becoming able to characterize my material just by looking at his stress-strain curve…
But that’s actually not as difficult as it seems and it is a skill very useful to have when you are an FEA Analyst!
Why are material properties so critical in your FEA Analysis?
One thing that I understood very quickly about FEA simulation is the concept of garbage in – garbage out
In one word: If you input garbage in your FEA System, you get ALWAYS garbage at the exit.
No need to say that one of the FIRST assumptions you do in FEA is about your material data
It seems simple… just a few fields to fill in and that’s it, right?
It may be sufficient to do that most of the time, especially when you are simulating parts in steel material…
But there is something I always emphasize ( whether in my blog or in my courses):
Applying something without thinking about it and knowing what it means and the assumptions that are made… isn’t something you would await from a real engineer
Engineers are creators and builders. You cannot build if you don’t understand how things work.
You could ask anyone to click on a button called « Al 6061-T6 » inside a software and choose an aluminum material.
Does this mean that it is correct? Nope.
If your role is to design part and systems composed of various materials, you have to understand the assumptions that are made about each of those materials.
Here’s a simple example…
Many types of aluminum’s have a nonlinear elastic range… which means that a big error will be introduced if you try to analyze them in the same way as a steel material.
If that’s obvious for you… you may stop reading, this course is probably not for you.
BUT (and that’s a big but)
If you are not sure that you understand all the material properties and that you are the kind of engineer or designer who wants to « get it right », then you should probably read this course.
To be frank with you, I believed myself that I knew everything about this topic before making this course for you, but I was surprised to realize that there were many topics that I actually didn’t understand as much as I thought I did (especially the part about failure properties and brittle materials…)
I had to go back to study and deepen my own knowledge before being able to make that knowledge extra-clear and comprehensible for you.
That’s why I know that you will get a lot from this course and that you will enjoy it!
Who am I by the way?
My name is Cyprien Rusu, I am a CAE engineer with more than 10 years of experience in FEA who wants to teach the right bases of FEA Simulation to designers, engineers and everyone aspiring to get it right!
Hundreds of FEA students followed my free FEA webinars on Youtube, read my blog articles on feaforall.com and joined my FEA courses to learn more and improve their understanding of FEA and become better engineers!
The FEA courses I create are the easiest to understand material available on the internet!
