Creep Analysis

[Anonymous]

Can Nastran-in CAD do creep analysis?

Cheers

Yes. See Section 18: Nonlinear Materials

Do you have a sample analysis or tutorial  I could have a look at ?.

Hi,

I will check if anyone has an example that can be shared.

Hi @John_Holtz ,

The link that you shared in an earlier reply mentioning that creep analysis is possible does not work anymore. Could you please direct me to the updated page if there is one?

Thanks in advance

Deep links to the online help don't work now and then. Goto the online help

http://help.autodesk.com/view/NINCAD/2017/ENU

Navigate to "Self-Paced Trainig" open "Section 14: Nonlinear Static Analysis" click to "Section 18: Nonlinear Materials".

You will find it also in later releases of the online help.

In 2021 the deep link works (at this moment):

"Inventor Nastran allows the definition of two other nonlinear material models, hyperelastic, for rubber and other elastomeric materials, and viscoelastic, for time-dependent response such as creep. Each of these nonlinear material models requires more detailed knowledge of those phenomena as their behavior is not quite like common structural materials."
