Hello Everyone,

 

Can we do fatigue analysis in the same fashion for rubber materials as defined in the tutorial of optistruct?

What extra care should I take?

 

Regards,

Bharat

    HI Bharat,

     

    What material properties do you have?

     

    If you have only E, RHo and G values, you can follow the same tutorial procedure.

     

    But if you want to include material non linearity you may have to force OptiStruct to run models with fatigue parameters using ANALYSIS>>CONTROL CARDS>> PARAM>>NLFAT >> YES which works with non linear quasi static analysis.

    Hello Merula and Prakash,

     

    @Merula - I am using the tutorials given in Hyperworks tutorials by Altair.

     

    @Prakash - I have basic properties such as E, Rho, nu, G along with stress strain curve.

     

    Thanks and regards,

    Bharat
