Hi everyone

 

I have a question

 

As you know, viscoelastic changes the Young's modulus and loss factor depending on the frequency.

 

Can I use sol103 for viscoelastic materials?

 

when i search google, it says i can do it using code aster. But I wonder if it is possible with Femap or Nx nastran.
