Capabilities of NX NASTRAN in fatigue ?

Hi All


I am interested in doing low-cycle fatigue analysis and life prediction.

Is this analysis option in NX Nastran, please?

Are there another supporting component in NX suite can support fatigue analysis, please?

Not at all, NX NASTRAN is a FEA solver, do not compute fatigue, you need either DURABILITY module under SIMCENTER 3D, or if you are "FEMAP with NX NASTRAN" bundle user you can take a look to winLIFE fatigue analysis module. Also you have LMS Virtual.Lab Durability.

Simcenter Durability is an add-on to Pre/Post that you can use to validate the structural integrity of your structural model over its entire life cycle under various simple or complex loading conditions.

winLIFE is a fatigue standalone software tool that is integrated also with FEMAP and takes advanced of stress results from NX NASTRAN solver, see

Read NX Nastran FE model and stress results (N load cases), define Time histories (for each load case), define material properties (Stress o strain). --> Calulate stress histories, make High cycle, Low cycle fatigue and crack propagation fatigue analysis

Is there a trial version for this software or not. I could not find that in the website
