Simulating with Aluminium 5083

[Ex_Machina_Engineering]

In the material properties for cold formed 5083 aluminium the data in fusion says:

Yield Strength: 280+ Mpa

Ultimate tensile strength: 375+ Mpa

These values are closer to structural steel and a bit of online research gives numbers of 200 and 270 respectively. Are the values in Fusion correct? Has anyone else ever noticed this?

Thats does seem high but with any FEA software, it is best to create custom materials if you know the properties of what you will be using.

The big difference between steel and aluminum is the elastic modulus. Steel should be about 3x that of aluminum. If you are running a linear elastic simulation the stresses will be accurate regardless of what your yield strength is if the modulus is correct.

True, but safety factors and shape optimization will be all wrong...

Absolutely. That's why it's best to base it on actual material specs when you're to that point.

I'm still a bit surprised they're that high regardless.
