Hello,

I need special materials for the FEM analysis,

who can help me create a new material in NX10 or NX12?

What values are decisive for this?

 

 

Regards,

B.L.

hi @BenBroad

 

There are different values and parameters that I can enter.
Which do I have to enter so that the calculation runs properly.

The whole subitems "Festigkeit"strength, "Dauerfestigkeit" etc ...

 

I do not have to enter every value or parameter?

Of the steels, I know only a few properties like
E-module, tensile strength etc ...

 

or am I totally wrong? Smiley Very Happy Smiley Very Happy

 

 

I'm sorry for the complicated description

Hi @BachmannL,

 

You can add at much information as you like - you actually don't have to enter anything other than a name, however, if you assign a material with no properties, expect your results to reflect the same - i.e., if no density is given to the material, the body that is assigned that material will have zero density and mass.  If you choose to add this material to a MatML library, all properties that are not given a value will be added to that library with zero value (but they can be edited at a later date):

Create a dummy part and create a new material for it to see how NX uses that material and the properties you've define.  When you think you have sufficient properties added to your material, you can either create your own material library or add it to an existing library, so it can be used in other parts.
